It is not clear to me that the server will be able to support the
composed form of à or ø. Where is specified the conversion from
ISO-8859-1 to UCS? Nowhere.
If a server knows it cannot deal with Unicode Normalization, it should
either use an encoding form of Unicode (utf-8, utf-16), implement a
technology that uses directly IRIs (because Normalization is
introduced only when converting to an URI) or generate IRIs with
binary path data in opaque form (ie percent-encoded)
By the way, the server should be able to deal with both composed and
decomposed forms of accented character (or use none of them), because
I may type the path directly in my address bar (do you know what IME I
use?)
