Note: I only show Upper Case letters here (exception is the Kra of Greenland); please look at the glyph bands of the language sets you want to work with, to see the Lower Case letters >>> some can have different diacritics and other letters can look slightly different (for example the German ß, the Kra, ... ) !
Warning> I've used stylised diacritics, I didn't really work too hard to differentiate between caron, cedilla, comma, apostrophy (on UC these are distinctly different and can take another shape when used on LC).
I often want to add glyphs for another EU language and made this "font" as a visual support; as this is newly published I'm not 100% certain to have all correct glyphs for a language and shall verify on the 'net' whenever I want to add glyphs for a EU language. But even with this uncertainty I think it will help other members -- please let me know if I made mistakes or something is missing. Just remember to check yourself that all necessary diacritics are shown here. You could also clone this, add the missing glyphs and republish the improved version > Keep it cloneable to help people, please ;)
