I don't understand why the error message would refer to "\xA3" -- in the code you posted (at least, after I downloaded it from PM), lines 2 and 4 contain non-ASCII bytes where I would expect to see a simple ASCII equal-sign ("="). In both lines, the non-ASCII bytes happen to be "\x81\x81". Maybe your local copy has "\xA3" in these places, and there was some sort of conversion error when you tried to paste the code into your post?

Anyway, whatever text editor you use to write perl code, use it to replace the non-ASCII characters (whatever they are) with "=" on lines 2 and 4.
