I grew up in russia and every localized game always had godawful ugly thin fonts. I would always watch foreign gameplay videos with jealousy cause they had beautiful latin fonts.

Now it's been years since I played a game in russian (almost a decade at this point I think) and I am so glad I don't have to put up with that anymore. Once in a while I see a screenshot from a cyrillic-using language translated game and probably half of the time the fonts are still bad.

It's the same for some non-Japanese games who don't take the time to think it through, worse case scenario is when they use Chinese fonts.

Because Japanese and Chinese characters are slightly different, but Unicode decided to unify them under the same codes....

it's because whatever font stack to directx renderer middleware game engines were using was usually only developed for the latin script, probably the lowest common denominator of no diacritics either.

I remember that PES6 was the only PES to get Polish translation. The start screen wouldn't render correctly because the font was missing the glyph Ś.
