While this is tecnically true, I dare you finding a program that lets an user
create a filename in NFD form on Windows. On other hand, *right now*, Mac (or
better: HFS+) is totally broken with Subversion, because *any* filename
subjected to different NFC/NFD form is broken.

There is no silver bullet here. Both Linux and Windows allow to create two
files (in the same directory) whose names which normalize to the same name.
This is unsupported by HFS+. So you can't really "win".

But you can solve *most* problems by normalizing. As I said, I think that once
the Mac problems are solved, you're *very* unlikely to get a bugreport from a
Windows user.
