Hello Luke-Jr, you’ve been asking:
Are there any hexadecimal digits in Unicode?
Simply use the digits “0” through “9”, and the letters “A” through “F”; cf. <http://www.unicode.org/faq/casemap_charprop.html#13>.
For example, perhaps the digits used for John W. Nystrom's Tonal System?
I had to consult: <http://en.wikipedia.org/wiki/John_W._Nystrom#Tonal_System_.28Hexadecimal.29>, to learn about this system. Apparently, Nystrom's Digits for “9” through “F” are not encoded in Unicode, cf. <http://www.unicode.org/charts/#symbols>. I do not know, how successful Nystrom’s proposal has been, and I cannot assess whether his digits deserve to be encoded, in Unicode. If you think, these digits need to be encoded, you are free to propose that; for the procedure required, cf. <http://www.unicode.org/faq/char_proposal.html>. In any case, it would be problematic to unify Nystrom’s “9” through “F” cannot be unified with Unicode “9”, “A” through “F” (treating them as a glyph-variation, and font-selection, issue), for two reasons: • Unicode “A” through “F” are also used for spelling ordinary words; this would not be feasable with Nystrom’s glyphs; • Nystrom’s digit “A” looks exactly as the common, decimal digit “9”, which would render any special Nystrom font rather misleading to the reader. Best wishes, Otto Stolz
