For example the following filter in ICU: NFD; [:Nonspacing Mark:] Remove; NFC. Will remove all accents from characters. And it works for all Unicode characters. With a bit more thinking you can work with case variations also. There is also a locale-independant case-mapping module there plus various locale specific ones also. http://icu.sourceforge.net/userguide/Transform.html http://icu.sourceforge.net/userguide/caseMappings.html http://icu.sourceforge.net/userguide/normalization.html Have a nice day, -- Martijn van Oosterhout <kleptog@xxxxxxxxx> http://svana.org/kleptog/ > Patent. n.
