This proposition is not very different from the note "unicode-composition-for-filenames" or
what Peter S, Neels and others suggested, perhaps just combining 2 changes slightly differently.

Enforced by normalising to NFD before uniqueness checks during add operations (yes, might
be more expensive). There will be no unified normalisation, but the subversion server will
work like most filesystems; return what was given to it.

For compatibility, we cannot ignore existing repositories and working
copies which have filename
collisions. So we cannot enforce subversion servers and clients to
normalize filenames.
We must let users to choose whether filenames are normalized or not
per repository.
