printf(1) explicitly states that it works with ASCII and ANSI
X3.159-1989 (``ANSI C89'') character escapes, and it also notes:
Multibyte characters are not recognized in format strings (this
is only a
problem if `%' can appear inside a multibyte character).
Some platforms have a printf_l(3) which is locale/xlocale-aware, but
there doesn't seem to be a corresponding CLI utility which understands
Unicode/UTF8/widechars.
