Oh...! 'дх' is completely lost.

Actually, your investigation gives me a perfect workaround: I can
enclose the problematic words (where a diacritic sign appears in the
middle) in another language, say \textenglish{}. This way a proper
kerning is preserved. Losing hyphenation is not a big problem in
texlive-sr, since there's not many words with combining diacritics in

Ulrike, thank you for investigating this!
