Why do we need this for 'svnsync' in general?
I would guess the only case where we need it would be if the user really
asks us to translate the properties, which in general they shouldn't, as the
properties should be encoded correctly in the original repository.
Note that on Windows we don't use apr-Iconv any more. There is a Windows
specific implementation in our utf subsystem that makes the OS handle the
conversions for us without this dependency.
