Yes, this is most likely the case. Converting to unicode is required
by the TSS spec when entering a password through a popup dialog.=20
Axel, have you successfully entered a password through both a windows

from windows and use the sha-1 of that?  I'm just interested in
whether trousers unicode stuff was in use...

Thanks,
Kent
