The only problem we have is that 'svn' might try to internally convert
the filename from the "native" encoding. Because of the empty environment
in a hook script it will assume the native encoding is ASCII (LC_CTYPE
isn't set).

So the input conversion will fail if a UTF-8 path containing non-ASCII
characters is passed to 'svn' by the script. There's nothing the script
can do about that without knowing what the locale should be.

So we'll need to provide a way to set LC_CTYPE in the environment
of hooks.
