Absolutely agreed. My general recommendation is to have two vastly different concepts: "equality matching" and "searching". Equality is case sensitive and strict; NFC/NFD normalization is about all you can do. Searching, on the other hand, can be case insensitive, do NFKC/NFKD normalization, and can even (in many contexts) strip off diacritical marks altogether, allowing people to search for "resume" and find "résumé", or to search for "muller" and find "Müller". There can be a whole swathe of other transformations done in search normalization too (collapse whitespace, fold punctuation into a few types, etc), though of course you need to be aware of context. But IMO it's far safer to NOT define things in terms of "equality". ChrisA -- https://mail.python.org/mailman/listinfo/python-list
