First of all, test.txt is in CP1251 encoding, not KOI8-R ;-) Second, patch is plain wrong -- it replaces KOI8-R character codes with CP1251 ones. > If you run the test program you should see something like this (strange > looking text maybe because of the webmailer I use): > ---snip--- > Match small (RegEx with i flag): 0 > Match small (RegEx without i flag): 8 > Match for normal (RegEx with i flag): 17 > Match for normal (RegEx without i flag): 9 > > Case - Check for 'яѓјъшэ' > lc() => яѓјъшэ > uc() => ЯгиЪШЭ > lcfirst() => яѓјъшэ > ucfirst() => Яѓјъшэ > > Case - Check for 'Яѓјъшэ' > lc() => яѓјъшэ > uc() => ЯгиЪШЭ > lcfirst() => яѓјъшэ > ucfirst() => Яѓјъшэ > ---snip--- > > I'm told the "Case - Check" parts are correct with the patch, but not > without it (lc() -> lower case the entire string; uc() -> upper case the > entire string; lcfirst() -> lower case the first character; ...).

This is what test gives me (transliterated to ascii): Case - Check for 'pushkin' lc() => pushkin uc() => PUSHKIN lcfirst() => pushkin ucfirst() => Pushkin Case - Check for 'Pushkin' lc() => pushkin uc() => PUSHKIN lcfirst() => pushkin ucfirst() => Pushkin It seems correct for me... > If this is correct we've solved only a part of the problem.
