I don't know which characters are the problem, but based on my experience 
with snort I'd suggest that it is likely a list of specific characters that 
aren't allowed to be used without escaping them... What's likely happening 
is snort's parser treats certain characters as syntax elements and get's 
confused by them.

I suspect that if you want to use "pa$$word" as a password, you'd have to 
enter "pa\$\$word" to escape them.

Good candidates for characters requiring escaping are characters that are 
used as rule punctuation elements. The list I can think of and find by 
searching the docs and snort.conf are:

          # ! $ & =  ( ) : ; , - > < { } / \ | "
