Unusual yes, but logical in a way.  A 'bot that attempted to OCR the 
CAPTCHA would probably read the Pi symbol as "tt".  So it is much more 
difficult for a non human to read it.  The obvious problem is that while 
the average human can read the symbol, they can't type the darn thing. 

I proclaim using non-ascii characters to be very smart, in a totally 
clueless way!
