It is not really a problem, we only have to build up a DEBUG function
that converts to ascii before printing (and we should do the same with
utf8 too afaik), debug statement performance is not so important imho.

I agree, I hope also tridge may contribute to the discussion, as I had
many talks with him about this issue in the past and we agreed that
using ucs2 internally was the best compromise.

I tend to agree, but are we sure we always have a valid NT_USER_TOKEN
when we need to access the sam?
I'm thinking of accounts administration, migration, backup, and so on.

This document seem good, but I would really prefer to smb_ucs2_t types
in it :)
