Steven D'Aprano <steve+pyt...@pearwood.info> added the comment: This is not a bug, but an issue with the way the Unicode standard defines the lowercase of dotted I.
See #34723 Fortunately, Unicode will (hopefully!) fix this in revision 14.0, which is scheduled to be included in Python 3.10. Until then, perhaps the simplest way to solve this is that if you are processing Turkish text, change your call to .lower() to .replace('İ', 'I').lower() ---------- nosy: +steven.daprano resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43020> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
