Bug ID: 50175
           Summary: Path of Exile: some Cyrilic and Hungul text is missing
                    since Wine 5.20
           Product: Wine

Created attachment 68693

(from left to right) Cyrilic, Hungul, Thai (top down) Before, After

I did not fully understand the problem for its detailed description, but I have
already finished bisecting.
Several patches were adopted that day aimed at working with gdi32, but only the
last one gives this effect:
2d15ea5012e1fbd9e16a86c69d68b587128832ed good
5bdc6e0fe64222d8d7d383616f5e230928af011a bad

It looks like all the Cyrilic/Hungul symbols (except those on the buttons) are
missing and/or do not take up space.
I attach a picture that displays the "same" graphic element, in different
in-game localizations on different versions of wine.
**Thai hasn't properly worked before, but I decided to include it in the image
as it looks like the problematic commit is affecting its behavior too.

I recognized the font as FrizQuadrataITC that was used for Cyrillic text.
