You can't use character classes like that (atleast to my knowledge).
You have to specify the symbols you want to add, like
$[$%^&*()\\-_+=|\<>\[\]{}#@...
You have to "escape" some of the characters used by the preprocessor itself with
 \. These are \, -, [ and ]

>From JTR documentation:
There are some special characters in rules ("[" starts a preprocessor
character list, "-" marks a range inside the list, etc.)  You should
prefix them with a backslash ("\") if you want to put them inside a rule
without using their special meaning.  Of course, the same applies to "\"
itself.  Also, if you need to start a preprocessor character list at the
very beginning of a line, you'll have to prefix it with a ":" (the no-op
rule command), or it would be treated as a new section start.
