Regex to search for special characters in a string with some exceptions

Question

I was simply answered a similar (but not exact) question. Now I need help with the question mentioned below.

I want to write a regular expression that matches a character if it is not a word, not a number, and not a star (*). Thus, the characters [0-9][az][AZ] * should not match, and the rest should.

I tried to write [\W[^*]] but it did not work.

Answer 1

Try this instead:

 [^\w\*] 

Answer 2

 [^\w\*] 

Simple enough.

Answer 3

The simplest regular expression that matches a single character that is not one of those that you describe does not depend on any particular regular expression extensions would be:

 [^0-9a-zA-Z *] 

Answer 4

Please try the following regular expression:

 [\W_]
