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.
