When building a new database, I noticed that many characters are not displayed on the map, although they are normally displayed in the base menu. After passing a few tests, I found out a list of such symbols.
Here is the list: ~ @ ^ _ { } | А Б В Г (and all other Cyrillic letters).
There seems to be a problem with the font. Is it possible to change the font for base names to one that supports Cyrillic letters? Or make their input impossible for player base names.
