Regex for all PRINTABLE characters

Question

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. do

Answer 1

It depends wildly on what regex package you are using. This is one of these situations about which some wag said that the great thing about standards is there are so many to choose from.

If you happen to be using C, the isprint(3) function/macro is your friend.
