Need to case-convert non-ascii text

[Hammie]

LegacyDialog needs to convert the character name to uppercase.

Currently it is using std::toupper but this does not work correctly with non-ascii (i.e. Russian) characters.

Greetings @Hammie,
I was trying to help with this case, but since i am a begginer in this progamation stuff, i couldn't properly test my ideas and my reasoning (mainly because I couldn't clone the code).

I think i was going to the right way and found people with some similar problems. So i am leaving here an interesting find that i made that may help u (blog):
