[patch] accented characters in MultiListFields

Hi,

I maintain the Formulator package (zope-formulator) for Debian, and
one of our users reported the following problem and supplied a small
patch that seems to work.

Is there a better way to correct this?  If this change might cause
harm, please let me know so I can back it out.

Thanks.

The original bug report in Debian is
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=253430
but there's not much more there than what's above.

Thanks.
