System Information
Operating system: Windows11 Home 22H2
Graphics card: NVIDIA GeForce RTX 2060

Blender Version
Broken: 3.4.0 Alpha, f9113b7eb6, master, 2022-10-29
Worked: 3.3.1

Short description of error
As shown in the picture, in 3.4, some of the interface text does not match the Chinese writing, which seems to be closer to Japanese ? In contrast, version 3.3 and previous versions are roughly correct, but still have some errors. When the font is switched to Noto Sans S Chinese Regular, the display result is completely correct.

In Text Editor:

example.blend
NotoSansHans-Regular.otf

Thanks!

I’m away from home and computer right now (Blender conference). But in a nutshell the font we are using here is a “Noto CJK” font, which has glyphs for Chinese, Japanese, and Korean. But there are some “overlaps” in the languages in that some Unicode characters can differ between languages. I’m not currently sure which is the “default language” in the font file we are shipping but perhaps it is different from our old font. Fairly certain that the intent is that we set an OpenType “feature” called “locl” that selects an output language so that these characters use the right language-specific variant. Will look into this when I get back but will appreciate any advice or help if you have any.

Thank you very much! I have another question: The Chinese Font Thumbnails are showed as Japanese "あア亜" currently（In 3.3 showed as Chinese & Latin）. I think it would be more suitable to display Chinese Font in Chinese. Maybe it related to https://developer.blender.org/rB4e7983e07320

Yes, that is me too. For me to fix that I’d need your help. For testing of the font I’d need examples of characters that would definitely be in a Chinese font but would not be in one for Japanese or any other language.

Assuming we can test for such a font, what three characters would you like shown in the thumbnail? It can meaning or not (as long as it not at all offensive) but should show shapes well to help differentiate between the styles of different fonts.

Will confirm this for now and set to High as it's a regression and seems important to fix before release.

目前由部分字体显示为“布丁体”
我建议简体中文可统一用“简体字”
还有，繁体中文可统一使用“繁體字”，如同Windows操作系统那样。

Currently, some fonts are displayed as "布丁体"
I suggest that Simplified Chinese can be unified with "简体字"
Also, Traditional Chinese can be unified with "繁體字", just like Windows OS.

@Harley Acheson (harley) I think these three characters are appropriate

I’m away until November 7th.

Will looking to see if a single different version of the Noto CJK font can work with all the languages sufficiently for us. These all contain all the glyphs for Chinese, Japanese, Korean, but there are versions that have different defaults for language-specific variations. https://github.com/googlefonts/noto-cjk

We probably can’t do one way of switching, using the “locl” feature and “gsub” table, which is not exposed in FreeType - assumed to be done by a higher level by Harfbuzz and we aren’t ready for that yet.

Another solution is the versions of this font that treat them separately in the same font file. Basically looks like one font with multiple faces. But they remain smaller than separate fonts by internally sharing tables of shared glyphs. Might be easy but would also need a change in how our fallback works to check multiple faces but that should be done anyway.

Note also - if I take too long or get hit by a beer truck - that “reverting” to old behaviour should not require code changes, just replacing font files. For example just replacing our current main font with the old metafont, then deleting the CJK font. That would give us old font but with fallback to all the added symbols, new languages, and last resort.

Hi guys, I encountered this similar problem recently when doing my own programs with freetype, turns out freetype can actually handle fonts with different variants. If we implement this into blender it could be better for all CJK users because they all see their preferred variant. I haven't dug deep enough how blender handles that but here's what I did to extract chinese variant from the "combined" font file (with some references from freetype doc and some searches...) :

    //...
        FT_Face face; FT_Long i,num_faces; FT_Open_Args args; args.flags=FT_OPEN_PATHNAME; args.pathname=buf;
        if(FT_Open_Face(f->ftlib, &args, -1, &face )) /* Here use for checking how many faces are there. */  continue; /* Can't find file. */ 
        num_faces = face->num_faces; FT_Done_Face(face); int found=0;
        for(int fa=0;fa<num_faces;fa++){
            if(FT_Open_Face(f->ftlib,&args,fa,&face)){ continue; } /* Here use `fa` to select the index of desired face. */
            if(strstr(face->family_name,"SC")){ found=1; break; } /* Here we can switch depends on the language settings and use appropriate one. */
            FT_Done_Face(face);
        }
        if(found){ /* The face for SC variant is found.*/ }

I'm not sure if this is useful enough or not, maybe I could help implement a fallback method in BLF.
