You should refer RFC 3501 section 6.4.4 for search syntax.
Searched text must be specified by bare text (not MIME encoded one), and its CHARSET is specified.
It is not required that CHASET is same as charset used for MIME encode.

I feel that 2.2.13 just does not support windows-1251 yet.
(I can find it in both 2.3.18 and 2.4.12)
