Correct, it is apparantly libc itself, not iconv, but the point is if
clocale can, why not abstract it that way.

Because the textmode versions might not be installed on all systems, the
compiled versions might be OS specific, and if they ever change for linux
distributions you have another problem at your hand.

And IMHO it is not crucial enough to try to bypass libc.
