Hi, Gilles.

My guess is that mc has a small syntax error in the line you call garbage.

There are lots of possibilities, for one thing; and for another, the
syntax doesn't agree with what man printf would lead you to expect.

/usr/bin/mc is binary, so I guess you'd have to look at the source to see
if changing \0057 to \u0057 in two places there solves this problem.

If it does, there are probably more similar errors, maybe due to some
change in conventions.
