What do you mean by 'not usable'? Are they not showing correctly, or are the not typed at all. In many cases a large square shows up instead of the character.
could be the font doesn't support them.
Find a font that does and export with IrrFontTool.
Then load this Font through the GUIManager->GUISkin.
This might fix it.
