i didn't know about that.  i haven't finished reading even the wildly
out of date unicode standard i have (dating from some time in the 90s),
let alone a current version.

interesting the difference in attitude as between different languages.
for example, the glyph capital A appears in english, greek and russian
-- three different alphabets --- with the same sound (to first order).

yet a significantly different pair of glyphs (i in english and turkish)
apparently occupy the same code point.  (unfortunately, in the russian-
greek-english i speak from some knowledge of all three languages, but i
know no turkish at all, beyond its typographic issues and what spam in
turkish looks like...).

it would be interesting to know how.
