initializing ko-KR.json with translations via google-translate.
I doubt that existing fonts will cover any of these; but let's see.
import os
import json
l10nfile = './i18n/translations/ko-KR.json'
l10ndict = json.loads(open(l10nfile).read())
chars = []
for translation in l10ndict.values():
for char in [x for x in translation if x >= ' ']:
if char not in chars:
chars.append(char)
chars.sort()
print('\nTranslation file %s has %d unique symbols in its translations' % (l10nfile, len(chars)))
print('lowest unicode point: %s (or %d), highest unicode point: %s (or %d)' % (
hex(ord(min(chars))), ord(min(chars)),
hex(ord(max(chars))), ord(max(chars))
))
fontdir = './firmware/font'
for basename in [x for x in os.listdir(fontdir) if x.endswith('.bdf')]:
bdf = '/'.join([fontdir, basename])
print('\nChecking font file %s for existing/missing glyphs...' % bdf)
bdf_contents = open(bdf, 'r').read()
existing, missing = [], []
for char in chars:
if '\nENCODING %d\n' % ord(char) in bdf_contents:
existing.append(char)
else:
missing.append(char)
print(' existing: %s\n missing: %s' % (''.join(existing), ''.join(missing)))
if len(missing):
print(' missing %d unicode points between: %s (or %d) and %s (or %d)' % (
len(missing),
hex(ord(min(missing))), ord(min(missing)),
hex(ord(max(missing))), ord(max(missing))
))
Translation file ./i18n/translations/ko-KR.json has 327 unique symbols in its translations
lowest unicode point: 0x20 (or 32), highest unicode point: 0xd734 (or 55092)

Found NeoDungGeunMo neodgm as a ttf. Using otf2bdf to convert:
otf2bdf -p 14 -r 72 neodgm.ttf >neodgm-u14n.bdf
otf2bdf -p 16 -r 72 neodgm.ttf >neodgm-u16n.bdf
otf2bdf -p 24 -r 72 neodgm.ttf >neodgm-u24n.bdf

...Both of these font sets fully satisfy the script up top for ko-Kr.json's translations.
They both also satisfy other existing translations for: de-DE, en-US, es-MX, fr-FR, nl-NL, pt-BR, but they don't both work for vi-VN.
Only the original DungGeunMo-Regular font (dgm) fully satisfies vietnamese and all others including korean.
Followed instructions here
./bdftokff.sh dgm-u14n 8 14 > dgm-m5stickv.kff
./bdftokff.sh dgm-u16n 8 16 > dgm-bit_dock.kff
./bdftokff.sh dgm-u24n 12 24 > dgm-amigo.kff
For an indication of how much bigger these are with Korean added, a du -b ./firmware/font/*.kff:
110824 dgm-amigo.kff

As of Sep 9th 2023... This didn't work last month, and my last steps of editing the font.c file are not documented above. After building krux and switching to Korean, I saw no symbols. Used 3rd menu in login to get to settings and 3rd menu in settings to get to language.
