Will this match the unicode double ">" and the like?  Some people feel
the need to use these in their breadcrumbs and such.  If there is no way
to just filter out the foreign characters, I will use it.  

The other possibility is to lower permanently on each character that is
read to me, but this seems tedious and time consuming on my part and
likely slow for gnus to score.

Thanks for your help,
