fixed REG_ICASE for non-ANSI (Unicode) characters in the regular expression
* This was a combination of conversion loss and a too small color map.
* The test suite was actually broken for Unicode since we have to
`setlocale(LC_ALL, "")` for the libc Unicode handling functions
to work as expected. SciTECO already did that.
* Added test cases for plain Unicode (Cyrillic) characters in the
regexp and for character ranges.
