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

Try this:

[^a-zA-Z0-9 :]

JavaScript example:

"!@#$%* ABC def:123".replace(/[^a-zA-Z0-9 :]/g, ".")
