Sorry, I've already pushed this, but the test fails on FreeBSD,
DragonFly and NetBSD for out-of-range characters.

On these OSes (with or without my patch):

% LC_ALL=C zsh -f
% echo ${(#):-0x80} | hexdump -C
00000000  3f 0a                                             |?.|
00000002

This is due to the peculiar behavior of iconv(3). It converts
out-of-range character to '?' (0x3f) with return value 1,
indicating that one character is converted in "non-reversible" way.

I feel this is a "bug" of iconv(), but maybe better to implement
some workaround. I'm getting rather busy now, but hopefully I can
work on this within a few days.
