Indesign Bullets and Numbering format styles

I think the only solution for this, for all the languages that use a non-English alphabet, would be to create a specially mapped font (replace the standard Roman alphabet with the glyphs for the base alphabet of that language). Not too hard with a font editor, but tedious, easy to misuse without caution, and of course all numbering would be limited to those edited faces.

Yeah, for up to 27 entries on the list... 

But, as always, could be easily scripted - regular style + some separator between the letter and text.

Then, it could be anything - hexadecimal counting - 0-9A-F, icons, etc.
