Keybindings with non-ASCII characters won't load

[popugasik]

(Not sure if it is really an issue with non-ASCII, but) can't save binds with e.g. Kaomoji. Bind key in console and it will work. After game restarts lines with binds stop to load after first funny character (everything else still works fine).

How to recreate:

1. Type in console:

   bind - "say how (っ °Д °;)っ";
   bind = "say ü";
   bind -; bind =;
   

   "-" = "say how (っ °Д °;)っ"
   "=" = "say ü"
   

2. Restart game and check config.cfg:

   bind "-" "say how (っ °Д °;)っ"
   bind "=" "say ü"
   

3. Type in console:

   bind -; bind =;
   

   "-" = "say how ("
   "=" = "say "
   

4. Exit game and check config.cfg:

   bind "-" "say how ("
   bind "=" "say "
