this name may be added into inputenc/fontenc files, but current 8-bit
TeX font encodings have apostrophe as an alias for textquoteright.

but then, why use the name `cyrapos', when this is not a cyrillic-only
glyph (it is not located in the cyrillic unicode area, too). may be,
it is better to name it `textapos'?

i wonder, are there any 8-bit charsets for the Ukrainian language
which have `apos' as a separate character and distinguish it from
quoteright?

(in unicode-based encoding it is not a problem)

well, -- as long as the fonts are 8-bit encoded, i think that it is
unlikely that there will be a distinction. it is possible to use
16-bit fonts (and even bigger) with TeX (and with Omega).

will the Ukrainians distinguish apostrophe and quoteright in the input
encoding?

Best,
