Bare byte alerts but no non-ASCII characters!

[Julio Cesar Gazquez <jgazque0 () rosario gov ar>]

I'm looking at several "BARE BYTE UNICODE ENCODING" alerts, and wondering why 
are triggered, because as far as I understand it, it means there are 
non-ASCII, non percent encoded characters in the request.

However, all the bytes in the payload (at least as shown in BASE, and I don't 
have favorite suspects), are in the sub 0x80 range.

Any ideas about why this is happening? They aren't the only weird alerts I've 
got, but one of the most prevalent.
