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
