Hi, We have a Swedish customer who is seeing lots of DRUG_MUSCLE FP's. It turns out that __DRUG_MUSCLE1 is triggering on the common Swedish phrase "som är".
I looked at the regex and it seems that Perl treats är as having a word boundary in the \b sense between the "ä" and the "r" Maybe rewrite as follows (untested): body __DRUGS_MUSCLE1 /(?:\b|\s)[_\W]{0,3}s[_\W]{0,3}[o0\xF2-\xF6][_\W]{0,3}m[_\W]{0,3}[a4\xE0-\xE6@][_\W]{0,3}(?!\w)/i Regards, David.
