They are identical, apart from the ".svn-base". For example, the Ä
in VJ_Änderungsübersicht.doc is encoded by "A" followed by the two
bytes 0xCC88, which is UTF-8 for "combining diaeresis" U+0308. The
Mac seems to report file names decomposed.

And, tada, .svn/entries records the same file name using the bytes
0xC384 for the Ä, which is UTF-8 for "latin capital letter A with
diaeresis" U+00C4.

It looks like svn is grabbing the UTF-8 bytes from the system API and
the UTF-8 bytes it's stashed away in its entries file and comparing
them in a unicode-ignorant fashion, i.e. byte-for-byte, without
considering such niceties as character composition.

Indeed, it does.

Now what?
