I suspect the problem is somehow due to UTF-8 encoding.  The regular
expression engine may not be recognizing "é" as a valid word
character, so "cialis" appears to be surrounded by non-word characters
and thus matches the \b (word boundary) assertions.

I don't have an immediate answer for how to fix this one.
