Thanks for the link, I read the thread, but couldn't find any

There are very few OpenType fonts, which include pre-composed cyr.
accented vowels (CAV). Maybe exactly because there are no unicode
slots for them. Anyway, most imortant is that to produce quality CAV
by combining characters, an OpenType font needs features, that are
complicated. The right accent glyph must be chosen, if the vowel is
upper or lowercase, and then the accent must be positioned on the
right place above the vowel. The features are called "contextual
alternatives" and "mark positioning". No type designer even bothers to
do this, since the latin counterparts are already precomposed in the
font. I've checked for example the free ParaType-Sans and didn't found
such features. So CAV will always look suboptimal because of the
combining. Searching and Replacing combined characters in a text
editor is also a big pain, because one have to mark the both
characters (accent and vowel).

If so, than the accented kind of input writing like \` or \' is also
obsolete.
At least, we talk here about ca. 40 characters (including both greve
and acute variants). There must be some free slots in unicode. It will
make cyr. typesetting easier und better.
