I use runPrepUpdate to sanitize data going into my database.

What is necessary for sanitizing strings in input fields that I will write to tags?  
Should I implement a regex like Jordan's example here:

> If you can standardize on a single replace character, the regex becomes simpler. import re Comments = self.parent.parent.getChild("topspacer flex\_5").getChild("TextField\_0").props.text pattern = re.compile('[^a-zA-Z0-9 -]') Comments = pattern.sub('', Comments)
