Font localization

[kalinovka]

Hi!

 

Since the winter of 2025th I have been translating the "iris" mission. The translation is ready, but one thing - a problem with the Mason Chronicles font - prevents it from being published.

May the forum society help me with it's localization into russian language ?

 

Now it looks like this:

 

The file, that comes with the game, contains some letters. But not all of them. Wiki says:

Quote

At this point, the /russian/ versions of the seven bitmap shaders were frozen, and remain unchanged to the current day (unless DarkFate independently has made further alterations; beyond our scope here). [There was a 2021 touch of all font file dates... was anything changed then?]

While a Russian "mason_glow" font was created and shipped, it is merely a placeholder: an exact duplicate of "mason", in regard to the content of their DAT files and their sets of DDS files. Instead, the Russian deployment provides a substitute visual effect by rendering each character twice.

So the font modification was not finished 4 years ago.

 

Ok. I found russian version of Mason font in TTF:

And tried to converi it with  ExportFontToDoom3  and GIMP. I typed the command:

ExportFontToDoom3 masonchronicles3.ttf -size 12 -size 24 -size 48,

It worked, but TGA  font files contain only english letters:

 

 

Where is my mistake ?

@kalinovka,you may have better luck with ExportFontToDoom3All256, described and available here:

https://wiki.thedarkmod.com/index.php?title=ExportFontToDoom3

Beyond that, I haven't done anything personally with Russian fonts. Maybe the folks at DarkFate have further ideas about conversion from TTF to DAT/DDS (e.g., via some font editor?)

Thanks for your reply. I tried to run ExportFontToDoom3All256. Result is the same. The cause is that it takes only positions 0 -255 from the TTF. But cyrillic letters are located at 1025 - 1115 positions.

@kalinovka, probably no quick solution. I imagine, with a font editor that reads/writes TTFs, you could relocate the Cyrillic down to the 0-255 range in a custom TTF, which could then be processed by ExportFont3All256.

Or, if you know C++, you could make a variant version of ExportFontDoom3All256 with a different input range (both start and end) in the loop.* The wiki page contains a link to the source code for a Visual Studio build.

In either case, you'd want to order the glyphs (or glyph processing) as Win-1251 (and TDM) expects, so the generated .DAT files would require minimal fixup.

* Specifically, you'd start with FontExporter.cpp, and in function FontExporter::export_, change the loop indices of:
    // Export all characters.
    for (int characterCode = 0; characterCode < Font::numCharactersToExport; characterCode++)

  ...

But if that was all it took, I'd be very surprised.

[Geep]

@kalinovka, I'm assuming your TTF font codepoints are those of Unicode. A conversion to Win1251 would use this map:

https://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WINDOWS/CP1251.TXT

The lower 128 are just ASCII, where Unicode and Win1251 use the same number.

The upper 128 contain both the 90 codepoints you mentioned (starting with 1025 aka 0x0401), interposed with other characters. A proper rendering for TDM would include all these characters.

It is possible that some old-school font editor already has an export profile for Win1251.

As for hacking up a variant of ExportFontDoom3All256, you'd need to write a static array, holding Unicode values from CP1251.TXT. You could just do the upper 128 if you want, as shown next.

Example:

const static unsigned long UnicodeFor1251::array[] =
{
  0x0402, // 0x80 CYRILLIC CAPITAL LETTER DJE
  0x0403, // 0x81 CYRILLIC CAPITAL LETTER GJE
  ... // more tedious or fancy editing here
}

Then the code loop would be something like [NOT TESTED]:
 

    // Export all characters.
    unsigned long sourceCharacterCode;
    for (int outputCharacterCode = 0; outputCharacterCode < Font::numCharactersToExport; outputCharacterCode++)
    {
        if(outputCharacterCode < 128)
            sourceCharacterCode = outputCharacterCode;
        else
            sourceCharacterCode = UnicodeFor1251[outputCharacterCode - 128];
        bool okay = exportCharacter(sourceCharacterCode, outputCharacterCode);
        if (!okay)
        {
            std::cerr
                << "Error: Unable to export character " 
                << getCharacterCodeString(characterCode) << "."
                << std::endl;

            return false;
        }
    }
    ...

Further down in FontExporter.cpp, more changes...

bool FontExporter::exportCharacter(unsigned long sourceCharacterCode, outputCharacterCode) // WAS single parameter characterCode
{
    Doom3GlyphDescriptor* doom3GlyphDescriptor = 0;

    // Get the index of the glyph that represents this character.
    int glyphIndex = self.font->getGlyphIndexForCharacterCode(sourceCharacterCode); // WAS characterCode
   ...
                // Create a descriptor for the current glyph.
            doom3GlyphDescriptor = &self.doom3GlyphDescriptors[outputCharacterCode]; // WAS characterCode
   ...
}

After a successul export, there's still lots more testing and tweaking to be done, e.g., with datBounds, refont, if you want best character spacing and presentation.
Also, TDM treats codepoint 0xFF specially, as mentioned in https://wiki.thedarkmod.com/index.php?title=I18N_-_Charset

Hi! Thanks for your reply. I am not a programmer at all (I graduated foreign languages faculty 20 years ago), so these things look tricky for me. Bu I will try all my best to patch the font.

It is interesting that Carleton font has been already converted to dds with all cyrillic letters. But who had done this work, I was not able to find.

I temporary changed Mason to Carleton, but I don't like the result. So I will continue my experiments.

The task of mission translation seemed simple for me, but for months later it look like a real quest.

If it happens successfully, at least it allows to update fonts in the next version of TDM..

 

One more question - may you tell me how to transform dat files to dds ?

I used the refont ulility, but it creates only a dat file. What should be done next ?

Yes, refont just makes it easier to make changes to a .dat file (via human-editable .ref file).

To transform your .tga's into .dds, either -

• use a converter program (See https://wiki.thedarkmod.com/index.php?title=DDS_Creation_with_ATI_Compressonator)
• (recommended) use an image editor, most commonly GIMP (Photoshop will also work). You can read in and then export each file separately.

But more typically, with GIMP, all the .tga's associated with one of the three TDM-supported font sizes are read in as separate layers, to a common GIMP project file (saved as an .xcf file). Ordinarily, you set only 1 layer visible.

If you do any bitmap editing, the .xcf file becomes in effect the source master. Having all the files together as layers makes it easier to move a glyph (or copy parts of glyphs) from one layer to another.

You use GIMP's Export feature (you specify the .dds extension up the top entry part to tell it the format). Be sure to generate mipmaps.

Evidently a significant portion of the Cyrillic work was done by Keeper_Riff (in conjunction with Tels) back in 2011. These folks are not active in TDM these days.

Keeper_Riff outlined a workflow, starting with FontLab to edit TTF files...

[Geep]

Regarding the existing Russian version of TDM's MasonAlternative font, this had a different origin than those Russian fonts processed by Riff_Keeper.

Tels created this in 2012. He started from bitmaps of an ASCII Mason font, then used his Perl patch program to copy selected ASCII glyphs (that resemble in some way Cyrillic) to new font "MasonAlternative". See https://forums.thedarkmod.com/index.php?/topic/12863-translating-the-tdm-gui/page/15/#findComment-274617

In GIMP, he flipped or otherwise hand-edited to make them Cyrillic. He said, "There are still a few dozen missing, but this is enough to render the two headlines we have (New Mission and Setting)"
https://forums.thedarkmod.com/index.php?/topic/12863-translating-the-tdm-gui/page/15/#findComment-274623

This accounts for the incomplete coverage.

Speculatively, he took this approach because it couldn't find a Mason-style TTF font with both Russian characters and an acceptable license (e.g., public domain, or at the least freely redistributable for non-commercial use).

@kalinovka,I wonder what the licensing is for your masonchronicles3.ttf.

[kalinovka]

@Geep  ,

thanks for your answers.

 

Today I spent 3 or 4 hours trying to edit ttf. i used Font Lab 8 for it.

I opened the font file (it was in utf encoding). Then I tried to recode it into cp-1251 and failed.

masonchronicles3.ttf has an unknown license status, of course. But if my attempts lead to good results, I can draw letters in ttf by myself.

Tels' unfinished files - are they still available ? Can I continue his work from where he stopped it ? That DDSes made by him are available in the TDM folders, but I have not found sources with .tda or ttf.

 

And I still can't understand how to convert DAT into TGA or DDS.

I haven't used Font Lab, but perhaps there's an online user community that can help.

Drawing font glyphs is challenging but yes possible.

I can help you with Mason files, but I need to find the right version... I'll get back to you.

As for DAT, think of it this way: a TDM file is described by BOTH DAT and TGA/DDS. DAT has the metadata needed for character spacing and scaling. TGA/DDS has the glyph images.

Hi. I got the filetoday and will examine it tomorrow. Thanks! I will try to modify the font (at least, a couple of letters) and then test it in the game.

[Geep]

Just to complicate your life, there are 3 additional aspects to consider about the circa-2014 Mason files, and subsequent circa-2017 improvements to the 'english' version perhaps applicable to your work. (These issues are covered in the wiki "Mason Font" article, with a bit more in my "Analysis of 2.12 TDM Fonts", https://forums.thedarkmod.com/index.php?/topic/22427-analysis-of-212-tdm-fonts/. The 2017 changes can be seen in the *current* 2.13 TDM English Mason files.)

1) Need for custom DAT-scaling on certain Mason characters
The source TTF had upper-case and lower-case characters that were early-on considered too similar to size. So (before 2014) in the DAT, selective per-character scaling was used to differentiate them.  See https://wiki.thedarkmod.com/index.php?title=Font_Metrics_%26_DAT_File_Format#Per-Character_Font_Scaling for details.

As you add new characters, you should do likewise (relatively easy with refont).

2) Creating the "glow" of mason_glow

How Tels created the glow (for 'english' carleton & mason) is discussed in reasonable detail here:

https://forums.thedarkmod.com/index.php?/topic/12863-translating-the-tdm-gui/page/5/#findComment-262661

That could be done for Russian too, which I recall currently fakes a glow, and possibly would require a minor GUI or engine code change to use.

Note: To best accommodate glow and retain GIMP-visualization-alignment between base and glow characters, Tels moved some base characters within their bitmap, to keep their glyphs 2-3 pixels away from any bitmap edge. You should consider this when placing new base glyphs.

Note: For the 3 mason bitmaps doubled in size circa-2017 as discussed next, the mason_glow bitmaps were also doubled.

3) Extensive bitmap editing to solve main menu character jaggedness.

On Oct. 5, 2017, @Springheel in https://forums.thedarkmod.com/index.php?/topic/19129-menu-update/#findComment-412921 said:

"Looking at the Mason fonts, it looks like they were super low res to begin with, and were then just resized [presumably referring to per-character scaling], making them even worse. I'll see what I can do." [Further on, referring to fonts in the TDM menu system:] "It appears that resizing the dds file to make it higher res is possible, so I'll proceed."

Later, on Oct 13, 2017, he concluded within a "More detailed list of changes: "Updated the menu fonts, which were surprisingly bad before"

Unfortunately, I couldn't find details on how this work was actually done. I assume the bitmap editing was all done in GIMP. It started with doubling the size of certain bitmaps from 256x256 to 512x512. This was done for the first 3 bitmaps (i.e., those with ASCII, some Latin-1). Then characters were made more crisp and smooth-edged. How? Dunno. Also, some odd but harmless artifacts happened within GIMP (noted in https://forums.thedarkmod.com/index.php?/topic/22427-analysis-of-212-tdm-fonts/page/3/#findComment-499660)

@kalinovka, I hope you're making some progress on what you need for your Iris FM. I'm sorry if I scared you off with all my observations. Regrettably, I can't really offer you any significant work-sharing. I'm directing my time towards European fonts and translations, which overall are in far more meager condition that the Russian fonts and translations. But I do think what you're undertaking is valuable.

Hi! No, still no progress. I spent a month, but without any success due to the lack of skill and experience in works with fonts.

I Installed Font Lab, tryed to conver cp1256 into utf, but without any success. 

I to take a random free cyrillic font and convert it into dds. No result.

Thanks for your instructions, they helped to clarify me the basics of TDM sources.  I even translated some texts into my native language.

But I can't understand how to convert all TTF symbols into TDM DDS (utilities work only for english letters). I think ExportFont3All256 should be patched.

Or another variant - to delete all latin letters from TTF file, and to leave only cyrillic. i tried to do that, but  result is the same.

The letters and simbols are absent but the cells in the file don't disappear.  They are empty.

I perform different experiments, and have not succeeded yet.

 

 

[Geep]

Perhaps I can help move you along.

As you know, for TDM 2.13, in tdm_fonts01.pk4/dds/fonts/russian/mason/ there are 7 256x256 masonalternative_n_48.dds files (where n = 0 to 6). There is also the corresponding tdm_fonts01/fonts/russian/mason/fontmage_48.dat

Suppose I arrange to generate 1 or more supplemental dds files, starting with n = 7. These would have Cyrillic glyphs that are missing (or where the existing glyphs would be better replaced with new ones). In advance, you would have to decide exactly which characters these are. To help with that, I have run "refont -stats fontimage_48.dat" (including the russian annotations file). [This crashed at first, so needed a minor bug fix; will release an update]

Here is the resulting raw analysis. You can see that Latin character glyphs standin for many Cyrillic ones... probably just fine in most cases. Other cases not so fine, or the character is missing as indicated by ".", " ", or hollow box.

DAT or REF file analysis here is primarily designed to benefit english/european fonts.
Counts reported are out of 256 character codepoints.
Counts of problems should be considered minimums, since no inspection of bitmap files (TGA or DSS) is done.

    Total Glyphs Needing Work (minimum): 84

Pass 4 - Detection of identical or significantly overlapping glyph boxes (other than Hollow Box, Zero Box, or <Space>).
    that share a common floor. One of the members is a likely base, the other(s) are likely accented character(s).
    For each of the latter, the accent may or may not be missing; that can't be detected by this program.

[Pass 6 not shown, not relevant to Cyrillic]

You will have to review these and the glyphs and give me a list of what is needed. For each item wanted, ideally include the codepoint in decimal & in hex, the Unicode number, Unicode name, and symbol. You can copy these from the analysis text, e.g.:

char 254 (0xfe) // 254 is U+044E CYRILLIC SMALL LETTER YU: ю

Going the supplemental route, rather than regenerating all characters, is lower risk (of screwing up the main menu) and less work.

I can try to hack up a special program version of ExportFontToDoom3All256 to generate the supplemental dds and associated dat

Then you have to -
- combine the two dat files (2.13 and new) by editing
- for the new glyphs, to be stylistically consistent, some characters will need dat-scaling by 120%; likewise baseline-shifting. All done by adjusting the dat file. I would use refont, but Font Patch could work too. datBounds can be used intermittently to visualize the results.
- it would not surprise me if some characters need their bounding box borders and/or xSkip values shifted, in the dat file.
- Sometimes too, the generation process puts glyphs too close to the upper or left edges; those could be moved with GIMP (then dat changed to match).

Let me know if this workplan is of interest.

@kalinovka, FYI the program will be named ExportUnicodeFontToDoom3.

[Geep]

That discussion earlier about doubling some Mason dds to 512x512... I got a little confused. That applies to only the 'english' set (that includes Cyrillic glyphs too), not the 'russian' set, which is all 256x256.

As you know, for TDM 2.13, in tdm_fonts01.pk4/dds/fonts/russian/mason/ there are 7 256x256 masonalternative_n_48.dds files (where n = 0 to 6). There is also the corresponding tdm_fonts01/fonts/russian/mason/fontmage_48.dat

Suppose I arrange to generate 1 or more supplemental dds files, starting with n = 7. These would have Cyrillic glyphs that are missing (or where the existing glyphs would be better replaced with new ones). In advance, you would have to decide exactly which characters these are. To help with that, I have run "refont -stats fontimage_48.dat" (including the russian annotations file). [This crashed at first, so needed a minor bug fix; will release an update]

Here is the resulting raw analysis. You can see that Latin character glyphs standin for many Cyrillic ones... probably just fine in most cases. Other cases not so fine, or the character is missing as indicated by ".", " ", or hollow box.

Font Glyph Statistics for Font MasonAlternate, in File:

    of 1/17/2021 5:57:51 AM

DAT or REF file analysis here is primarily designed to benefit english/european fonts.
Counts reported are out of 256 character codepoints.
Counts of problems should be considered minimums, since no inspection of bitmap files (TGA or DSS) is done.
Itemizations include annotations from 'ref_char_annotation' file.

For this DAT or REF, the glyph in the upper left corner of bitmap 0, typically used for missing characters, is
assumed to be a 'Hollow Box' glyph.  (It is not the <Space> character.)

Specific tests for these and related 'Zero Box' are:
    'Hollow Box' = glyph's 'shadername' is <fontname>_0_<size>.dds only, and s & t are zero, but not s2 & t2
    '<Space>' = same test as 'Hollow Box', but pointed to by char 32 (0x20)
    'Zero Box' = No glyph box (s, t, s2, t2 all zero)

Pass 1 - Handling of unprintable/unsupported/missing codepoints,
    indicated by 'Hollow Box' or 'Zero Box'.

    Totals:
            Out of 33 expected in lower range (i.e., first 32 control characters + 127 (0x7f) Delete), and shown as...
        33    ...Hollow Box
        0    ...Zero Box
            Out of 4 expected in upper range (0x8f & 0x9f Undefined, 0xa0 NBSP, 0xad SHY), & shown as...
        2    ...Hollow Box
        0    ...Zero Box
            Undesirable in lower range, and shown as...
        0    ...Hollow Box
        0    ...Zero Box
            Undesirable in upper range, and shown as...
        30    ...Hollow Box

[Pass 6 not shown, not relevant to Cyrillic]

You will have to review these and the glyphs and give me a list of what is needed. For each item wanted, ideally include the codepoint in decimal & in hex, the Unicode number, Unicode name, and symbol. You can copy these from the analysis text, e.g.:

char 254 (0xfe) // 254 is U+044E CYRILLIC SMALL LETTER YU: ю

Going the supplemental route, rather than regenerating all characters, is lower risk (of screwing up the main menu) and less work.

I can try to hack up a special program version of ExportFontToDoom3All256 to generate the supplemental dds and associated dat

Then you have to -
- combine the two dat files (2.13 and new) by editing
- for the new glyphs, to be stylistically consistent, some characters will need dat-scaling by 120%; likewise baseline-shifting. All done by adjusting the dat file. I would use refont, but Font Patch could work too. datBounds can be used intermittently to visualize the results.
- it would not surprise me if some characters need their bounding box borders and/or xSkip values shifted, in the dat file.
- Sometimes too, the generation process puts glyphs too close to the upper or left edges; those could be moved with GIMP (then dat changed to match).

Let me know if this workplan is of interest.

Hi! Geep, thanks for your reply. Due to a deadline on my work I am reading your answers only today.

 

Yep, it looks like somebody began font coversion via tranfer of existing latin letters to the cyrilic ones (that look the same as latin).

 

The plan looks hardm but lets try to do all we can.

 

During Friday and Monday I will make the list of the letters we have and those, that are absent.

[Geep]

Instead of creating the list with the format I mentioned earlier, it would now be more helpful to use a slightly different format, based on your custom edit of Unicode.org's "Format A" for cp1251.txt

The draft upcoming wiki page for ExportUnicodeDoom3, that explains this, begins...

Introduction

This 2025 offshoot of ExportFontToDoom3All256 is in response to a [request to help – link] extend TDM’s Mason 48pt font to include missing Cyrillic glyphs. The main idea is that the input TTF font would go beyond those that support just ASCII or ANSI, to include those that offer additional Unicode characters. It still limits output to a maximum of 256 characters, consistent with the DAT format.

To achieve this, it reads an external “unicodeMap” file, in [Unicode.org’s “Format A” – link]. This provides the mapping from the traditional 8-bit ISO or Windows encoding that TDM uses (e.g., cp1251 for Cyrillic) to the corresponding UCS (Unicode 16-bit) value. As discussed below, you can edit this file in advance, if you want to generate just a subset of glyphs.

New Command Line Arguments (in Addition to those of ExportFontToDoom3All256)

unicodeMap

Example:

-unicodeMap "./Test/cp1251.txt"

You can edit the unicodeMap file in advance, to specify which particular glyphs you want to generate by suppressing unwanted glyphs, either by:

•          Deleting an unwanted line (or block of lines) entirely, or
•          Prepending a “#” to comment-out the line.

Also, this file format allows the Unicode value (e.g., “0x1234”) to be replaced by 6 space characters, when the ISO or Windows standard leaves that character undefined.

In all 3 of those cases, every suppressed character in the output DAT file will be represented by the glyph that the font uses for U+0000. A hollow box is common.

[additional arguments planned]

So in my testing so far, I created a "cp1251upperhalf.txt" file, with all the lower-half ASCII lines deleted. Seems to work with some random Unicode font (Lucida Sans Unicode). Beyond that, for your work, probably commenting out individual lines with a starting "#" would allow more flexibility.

[Geep]

I might not have been clear, that the link in the purple text above goes to standard cp1251.txt file that you need to edit.

Evening!

 

i have not read your replies yet. But today during my lunch time I analized the .dds files for Mason alternate font (files malonalternate_0 .dds - masonalternate_6.dds).

What do we have - masonalternate_6.dds and masonalternate_5.dds do not have cyrillic simbols - only special letters like accent aigu and accent grave for French.

masonalternate_4.dds  - 2 cyrrilic letters (Д, Ё and the same French symbols)

masonalternate_3.dds - 4 cirrylic letters (д,р and special symbols )

masonalternate_2.dds - mainly latin letters (u, V,W,X,Y, J,L,R,S.P,T,Z) and some cyrillic - н,л,м,и, г,Ф, я,з

masonalternate_1.dds  - latin letters (A.D,F,G,H,j,S,K,I,L,M,F,N,i,R,T,e) and cyrillic (Ж,Г,Р,И,Ф,М,Й)

masonalternate_0.dds  - cyrillic letters only (а,А, в,В,ь,Ь,ъ,Ъ,е,В,З,С.Э,Б) plus numbers from 0 to 9 and special symbols.

Probably we need to setup a shared spreadsheet to track status and decisions on each letter. I haven't used Google spreadsheets before (only Google docs & Excel), but could probably set one up, initialized with cp1251.txt data. If that's of interest to you.
