I think Craig understands that - how do you intend to call APIs from the
command line? (Yes, rundll probably but ok).
Otherwise, could you explain a bit more?

BTW: IIRC, there was a huge discussion about using the unicode API for
(once again IIRC) exactly the file deletion/manipulation API calls in
the FPC list. @Richard: you could have a search through there...
