Fair enough - POSIX does not require the existence of a multibyte
locale; an embedded system that provides only single-byte encodings can
still be POSIX-compliant.  But POSIX _does_ require that tr be
locale-aware, and therefore if an implementation provides multibyte
locales (which most desktop glibc-based GNU/Linux systems do), then tr
should honor those locales, including multibyte character support.

We're in violent agreement on this point :)
