Single byte locales collation works through strcoll() via chains, i.e.
seek all chains starting with given letter. Multibyte locales collation
currently is not implemented and can't be properly implemented under
existen single byte framework (it will consume resourses badly in that
case). I know semi-hacking attempts to implement multibyte collattion via
single byte one, but all they are only for small ASCII + national alphabet
subset, rest of Unicode left unsorted.

IMHO single byte collating will be obsolete soon when Unicode collation
will be implemented as SoC project, we needs something like ICU library
which performs as described below, i.e. unified sorting for all possible
