--- Comment #3 from D Ruth Bavousett <ruth at bywatersolutions.com> ---
It might be better to use this:

$searchfield =~ s/\p{IsC}//g;     #Toss out control codes, Unicode compliant

Fridolyn's patch would toss *some* non-word characters--spaces, tabs, newlines,
and formfeeds--when they appear at the ends of the string, but would not deal
with escape characters or other undesirable inputs.  Using this statement would
express the original intent in a fully-Unicode-compliant way.  Suggest changing
the patch to the example above.  It will pass letters, marks, numbers,
punctuation, symbols, and separators.

Chris, your paranoia is a good thing! Any of the other classes of character
probably are okay--although most won't match anything--but the control codes
are probably a good thing to toss out.

(Note: I haven't tried this myself in the Koha context; I've used it elsewhere.
 Definitely, someone wants to TEST THIS.  It's pretty arcane.)
