Regex to find special characters in a String with some exceptions

Question

I had just got a similar (but not exact) question answered. I now need help with this question below.

I want to write a regex to match 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 any others should.

I tried writing [\W[^*]] but it doesn't seem it works.

I hope I made it clear. but if not, I apologize. Thanks much for the help.

Answer 1

Try this instead:

[^\w\*]

Answer 2

The simplest regular expression that matches a single character, that is not one of those you described, independent of any particular regular-expression extensions, would be:

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

Answer 3

[^\w\*]

Simple enough.
