I have some validators that in Java and PHP that are using this :print: character class in their regexes to validate input lengths. Any human readable input is valid as long as it doesn't exceed a limit.

In the .Net part we are using the word (\w) characters class. This lead to a bug where lots of characters weren't matched by the .Net regex (ie. #, currencies, so on).

The question is: is \s\S a valid equivalent for :print:? If not what are the other options I have?

Would using \P{C} work? It would allow all except any control characters since I assume everything else would be "printable characters"? – Sami Kuhmonen Feb 18 '17 at 10:42
Do you use the `/u` modifier in PHP and `Pattern.UNICODE_CHARACTER_CLASS` in Java? – Wiktor Stribiżew Feb 18 '17 at 11:07
@WiktorStribiżew, I don't – Adrian Iftode Feb 18 '17 at 11:12
Ok, I have found a post that should provide enough answers. In your case, you can use `[ -~]`. – Wiktor Stribiżew Feb 18 '17 at 11:14
Thanks, I'll give it a try. – Adrian Iftode Feb 18 '17 at 11:16
