Yes. Most likely.

Thanks, that is a very helpful analysis (However, it does not solve the
problem, but it might be a point from where to go further.)

Why to convert it at all? Its the same encoding (or no encoding) on the
command line and the file system. Wouldn't it be better to just pass
that names from one subsystem (the commandline parsing) to other (open
the (initial) input file) without changing the encoding at all? Using
»unsigned char *« inside the software?

That would solve the problem and would be more obvious to the user in
any usecases. (With UTF-8 the there is also no conversion to be done.
It can also fill inside a unsigned char string.)

Too much trouble. And I will not go into details. One part of the detail
is that I don't like UTF-8 personal. :-)

Partly. It even helps way around to have beautiful names from UTF-8
strings in a latin1 environment. :-)
