As I showed, even for Latin letters, the trick of "if astring.lower() == bstring.lower()" doesn't *quite* work, although it can be "close enough" for some purposes. For example, some languages treat accents as mere guides to pronunciation, so ö == o, while other languages treat them as completely different letters. Same with ligatures: in modern English, æ should be treated as equal to ae, but in Old English, Danish, Norwegian and Icelandic it is a distinct letter. Case-insensitive testing may be easier in many non-European languages, because they don't have cases. A full solution to the problem of localized string matching requires expert knowledge for each language, but a 90% solution is pretty simple: astring.casefold() == bstring.casefold() or before version 3.3, just use lowercase. It's not a perfect solution, but it works reasonably well if you don't care about full localization. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
