Is there a special regex statement like w that denotes all printable characters? I'd like to validate that a string only contains a character that can be printed--i.e. does not contain ASCII control characters like (bell), or null, etc. Anything on the keyboard is fine, and so are UTF chars.

If there isn't a special statement, how can I specify this in a regex?

Very late to the party, but this regexp works: /[ -~]/.

How? It matches all characters in the range from space (ASCII DEC 32) to tilde (ASCII DEC 126), which is the range of all printable characters.

If you want to strip non-ASCII characters, you could use something like:

$someString.replace(/[^ -~]/g, '');

NOTE: this is not valid .net code, but an example of regexp usage for those who stumble upon this via search engines later.
