everything on your keyboard is monospace, 5x9 pixels. some special unicode characters are two spaces wide though, so the font is not entirely monospace. there are no characters that are not either six or twelve pixels wide (including spacing)
GS Unicode is a project I'm working on so (almost) all languages get support! With 14,564 non-spacing characters, this font is finished (as of Unicode 11.0). Please tell me if some of the characters aren't working. I'll try to fix them as best as I can!
