Text Field Validation Pattern

Hi, does anyone know if there a character for a text field pattern that can be used for alphanumeric characters, commas, periods, and spaces? Basically anything the user puts into the box gets formatted?

Here's the validation patterns I started with:

text{', '0}|text{', '00}|text{', '000}|text{', '0000}|text{', '00000}|text{', '000000}|text{', '0000000}|text{', '00000000}

Problem occurs when a user enters values that may contain a space or comma, example (PE, LEED) it doens't validate.

Any thoughts? I'm sure there is a way to format this with javascript, but I'm not saavy enough to do that...

Thanks,
