Cleaning up a TV output

I've been trying to find an answer to this question, and it seems like there should be a simple 'output modifier' solution.

I want to use a page's pagetitle as a body class, however, I can't seem to find an easy way to strip out all non-alphanumeric characters besides underscores or hyphens.

Ideally, I want to replace all spaces with dashes, and remove anything else (that isn't a letter or number).

How do I do this? There doesn't seem to be a string output modifier that I can use to accomplish this seemingly simple task.

How about using the alias instead of the pagetitle? It could still contain numbers, but numbers are acceptable in class names as long as the first character is a letter.

Actually that's a decent idea. Not sure why I didn't think of it. Though I found, I had to add some characters to the Friendly URL filter in setup to clean it a bit more (commas, exclamation marks, brackets are all still allowed by default).

But that use-case aside ... do you know of a snippet that would sanitize text to strip out all but alpha numerics? I found some examples online, but they didn't work for me (I'm not a programmer, so I wasn't sure what I was doing wrong).

Thanks for your response, Bob! I very much appreciate it.
