I do not quite understand the rationale behind not converting to UTF-8
on Posix platforms. I naively though I got UTF-8 in argv because my
system is convigured in UTF-8 but I discover that this is not
necessary always the case. In the example you highlight, I do not see
the difference from the Windows case. You could convert to UTF-8 in
argv and back to the local encoding in nowide::remove. I understand it
is not efficient if you do not really use the content of the filename
but if you have to write, say an xml report in UTF-8, you would have
to convert anyway.

Today, what is the portable way to convert argv to UTF-8? i.e. without
having to #ifdef _WIN32...?
