Is it possible to specify that you don't want a specific character at a specific position in a regular expression?

In otherwords I want it to return true if the string is "blahblahblah" but not if it is blahblahblah[" and only that one character should be disallowed.

/blahblahblah[^[]/

[^abcd] matches anything but abcd.

Is there no way to only specify that you don't want that specific character?

Thats exactly what it is. [^[] would match any character but [ i.e. the reg ex would not match if there is a [ in it (in turn disallowing it).
