I didn't know the function is only for ASCII characters until
quite recently.  It is because the function looks like a generic
function and works with non-ASCII characters after a fashion.
In addition, I cannot imagine who needs the voodoo function.  It
seems very much personalized for (by?) someone.  Why isn't it
sufficient to extract and separate name and address portions
simply without any modifications?  It can be done later if
needed, though.

3) Disable the voodoo function by default.  Since using the
   following form seems helpful not to break Japanese names.

   (eval-after-load "mail-extr" '(defalias 'mail-extr-voodoo 'ignore))

   Furthermore, I think the voodoo function should be moved to
   the language or the international subdirectory.
