Dear Colleagues,

Would it be advisable for TeX to adopt the neat term
\cyrapos for the important character/glyph "apostrophe" that
has letter status in Ukrainian?  The term comes from
the SGML character entity name "apos".  See below.

My copy of the TeX file "cyinpenc.dtx" uses the term
\textquoteright which refers to another MUCH rarer
character. I venture to predict that there will be an ever
clearer distinction at all levels between the diacritic
\textquoteright (unicode 2019) and the letter that I
propose calling \cyrapos (unicode 02BC).  Would someone
care to predict whether the two glyphs will forever
coincide in TeX fonts? How should all this be accommodated
in Cyrillic TeX?

           Cheers

                 Laurent Siebenmann

PS.  Maksym Polyakov <mpoliak@pcomp.nauu.kiev.ua> has offered
me (privately) the following outline of the usage of
\cyrapos:
