(Sorry for the top-post, but I've had enough of this thread.) Can we take this offline to a bit-bucket somewhere, and maybe point the original poster to a basic course on language and locales and character sets? This thread has gone on far too long, and has no relevance for anyone outside of the United States and their weird and incorrect use of their own language. I'm certainly tired of the repeated assertions by the original poster that he is right and that the rest of the world needs to conform to his obviously-incorrect viewpoint.
