Starting with the fact that 'main' can only receive argv[] encoded in
system codepage.

In any case, the tricky part in this case is not that we receive the
leading directories ANSI-encoded -- this is a known limitation of
Emacs on Windows, regardless of symlinks and pdumper look up -- the
tricky part is the resolution of symlinks in argv[0].  We have already
code for that, see chase_symlinks, but it wants to receive file names
in UTF-8.  So some recoding of file names is in order, and then
testing.
