Regex, every non-alphanumeric character except white space or colon

Question

How can I do this one anywhere?

Basically, I am trying to match all kinds of miscellaneous characters such as ampersands, semicolons, dollar signs, etc.

Answer 1

[^a-zA-Z\d\s:]

• \d - numeric class
• \s - whitespace
• a-zA-Z - matches all the letters
• ^ - negates them all - so you get - non numeric chars, non spaces and non colons
