You said that cmd.exe is unicode aware. If it is then it can show those
characters just fine. Only if it isn't then it can't show those characters.

Because every path passed to svn is converted to utf8 on input and only
utf8 strings are passed around internally in the svn lib.

Also the fact that it works if you 'cd' into that dir clearly shows that
svn.exe can deal with such paths, because not only are the paths
converted to utf8 on input but also all relative paths are first
converted to full absolute paths before they're passed to the internal
svn functions.

Nope. Skipping simply means the file was skipped. There can be other
reasons a file is skipped.

that doesn't matter: the content should be the same.

Just try it.
