Sorry for not exactly reading the Documentation, but I got stuck because the EFS flag seemed to be not enough for me and I wanted to get this straight before. But I think we've come a long way and the end i near ;-) >> Secondly, if you set the encoding to UTF-8, there's no need for >> unicode extra fields anyway. > > Except when your client doesnt recognize the EFS flag and thinks you'd > be using CP437 - but happily accepts the Unicode extra fields.

The implementation should be be straightforward, shall I prepare a patch or can you afford doing it at your own?
