I just had a similar (but not exact) question answered. Now I need help with the question mentioned below.
I want to write a regex which matches a character if its a non word, non digit and non star (*) character. So, the characters [0-9][a-z][A-Z] * should not match and the others should.
I tried writing [\W[^*]] but it doesn't seem to work.

To match a character having special meaning in regex, you need to use a escape sequence prefix with a backslash ( \ ). E.g., \. matches "." ; regex \+ matches "+" ; and regex \( matches "(" . You also need to use regex \\ to match "\" (back-slash).
?= is a positive lookahead, a type of zero-width assertion. What it's saying is that the captured match must be followed by whatever is within the parentheses but that part isn't captured. Your example means the match needs to be followed by zero or more characters and then a digit (but again that part isn't captured).
Definition and Usage The \f metacharacter matches form feed characters.
Try this instead:
[^\w\*]
