Well, yes. Accents and case are attributes of a character. (I'm using the unicode model here). So, to do a case insensetive match you take the characters, strip the attributes and then do the comparison. There are specialised routines which handle the denormalisation of the string for you so in theory you could even get specific about which accents you ignore. In practice I don't think people do that.
