I am years use ru_RU.KOI8-R. Now I try use ru_RU.UTF8 and got some
issuse (on 10-STABLE). 9.x and OS may have dufferent version of
software and don't touch this.

vi ~/tips.work
/home/slw/tips.work: unmodified: line 1; Conversion error on line 3

This is koi8 file in utf8 locale.

Other case -- file names in koi8 locale -- this is invalid in utf-8.
Change locale from C to utf8 may cause trouble.
This is (change from one-byte tu multi-bytes locale) may be do
individualy, after inspecting systems. This is may be OK for new
install, but not [automatic] for update/upgrade.
