How to reproduce.
1. Switch to the any 8-bit locale (KOI8-R as example).
2. Create text file with non-latin symbols in any charset (utf-8, cp1251, koi8-r, etc).
For example, cyrillic text:
{{{
ШШ
шш
шШ
}}}
where {{{Ш}}} is the upper-case letter (capital), {{{ш}}} is the lower-case one.
3. Open this file in internal editor or viewer.
4. Press F7 and enter {{{Ш}}} in the input line. Check the ""Case sensitive"" option off. Press Enter.

Result: only {{{Ш}}} is found, {{{ш}}} is not found at all.
Expected result: {{{ш}}} is as found as {{{Ш}}}.
