The character-search command accepts multibyte characters just fine, but
when reading input from a macro, multibyte characters are not processed
correctly. For example trying to invoke the macro defined with:
bind '"\C-f": "\C-]π"'
will fail to search and will instead type just the second byte of the
character (x80).
The following one-line patch fixes the behavior, but I'm not sure if this
the right place to do it.
