Yeah, I think that's what's happening for me on Linux as well.
Ever since switching from SDL_ttf and attempting to load "<locale>.ttf"
files, to SDL_Pango (now SDL2_Pango), we basically lost the ability to
use those fonts, and have been shipping them meaninglessly.  :-D  Oops!

I think this is okay (though we'll need to make sure it stays sync'd up
with Tux Paint, if/when we ever change anything!)

Way back in the day (literally 20 years ago, +/- a few months!) we
packaged up various fonts that were too big to include directly inside
Tux Paint, three of which are still available here:

  https://tuxpaint.org/download/fonts/

They include:

 * Korean (~10MB)
   The "ko.ttf" font file is a copy of "gulim.ttf" from the "Baekmuk" collection
   of Korean TrueType fonts, (c) 1986-2000, Baekmuk Font 21 Inc.
   (Came from Debian package "ttf-baekmuk", at the time.)

 * Chinese Traditional (~14MB)
   HanWangKaiMediumChuIn is a registered trademark of HtWang Graphics Laboratory
   (C)Copyright Dr. Hann-Tzong Wang, 2004.
   (GPL v2+)

   [Note: What we ship directly inside Tux Paint is a subset of another GPL
   font, "wp010-05.ttf", containing only the characters used by Tux Paint;
   it weighs in at 1.1MB.  Unfortunately, the Python script that generates it
   doesn't run under Python3.  Fortunately, I refreshed it back in early 2022.]

 * Chinese Simplified (~5MB)
   The "zh_cn.ttf" font file is a copy of "AR PL SungtiL GB",
   a high-quality Chinese TrueType font (gbsn00lp.ttf)
   generously provided by Arphic Technology to the Free Software community
   under the "Arphic Public License".

We used to have others available for download as well, but eventually
rolled them into Tux Paint itself.  I wonder if in this day & age it'd
be fine to simply include these last tree fonts directly inside
Tux Paint, too.  (It looks like it'd add about 28MB to the install size.)

I have no clue whether the Windows installers or macOS DMG from way back
in 2002 & 2004 still work properly with current Tux Paint!!!  I'd rather
not continue maintaining these separate downloads. :-)


Of course, going back to the beginning of this email, the main issue at
hand is Tux Paint, via SDL2_Pango, doesn't KNOW about these fonts yet.
At least, not for me, not on Linux!

I'll poke around.
