In the same way the [0-9] class is equivalent to \d, the [^0-9] class is equivalent to \D. Alphanumeric characters can be matched with \w and non-alphanumeric characters can be matched with \W.
Replace the [^a-zA-Z0-9] character class with \W.
You should replace the [^a-zA-Z0-9] character class with \W.
