Hey all,

Not sure how real the security risk is here:

     http://blog.omega-prime.co.uk/?p=107

Basically  he is saying that if you store a list of blacklisted files 
with names encoded in big-5 (or some other non-utf8 compatible encoding) 
if those names are passed at the command line, or otherwise read in and 
decoded from an assumed-utf8 source with surrogate escaping, the 
surrogate escape decoded names will not match the properly decoded 
blacklisted names.

All the best,

Michael Foord
