I think the issue (at least to start with) is the fact that
parse_nmb_name() and put_nmb_name() do not deal with the conversion
to/from unix charsets.

A quick fix would be to add a clistr_pull here - but I'm not sure how
things interact with the 17 char limit we have on the struct, and any
special meaning that has.
