As suggested by Linus, this function is not checking UTF-8-ness of the
string; it only is seeing if it is pure US-ASCII.

Thanks Junio,
that partly obsoletes the patch I'm working on.
And as I didn't manage to catch up, may I send the result of my review?
a) in readdir we die() when iconv_open() fails, and we could/should do
that in void precompose_argv() as well?
b) Should die(txt) be converted into die(_(txt)) to be able to
translate the message?
c) We can remove the save/restore of errno at one place, similar to this:
