No, it's not just that. Certainly, you could have files "X" and "=E2=85=A9" (the Roman numeral). E= ven if they look the same there is no problem (other than likely user confusion) in having both. However, the two types of "=C3=BC" are the same character, or at least functionally equivalent characters. They should be considered equal. But comparing them properly requires normalization (cf. http://www.unicode.org/unicode/reports/tr15/). OSX does normalization in its file system. GNU/Linux apparently does not. Emacs must also be doing some normalization... switch-to-buffer completion works on "r=C3=BCckerstattung" after all. Only `read-file-name' doesn't. Hmm, maybe this /is/ an Emacs bug after all. regards, Nikolaj Schumacher
