Cyrillic is not displayed in TextMeshPro

Hello dear.

Cyrillic is not displayed in TextMeshPro, squares are displayed instead of Russian letters.

I looked on the Internet for analysis of the same issue from other people, but I did not understand anything and did not help. In Asset Creator, it seems that Hex was correctly indicated, but still not.

Who can help me figure out what the problem is?!

You’ll need a font with Cyrillic glyphs - Google has a number of free fonts: Browse Fonts - Google Fonts
