The ',' I knew, I just didn't do a good enough job differentiating
between my special characters and the punctuation in the sentence. The
'=' was my problem; I was mixing regex and php syntax, since that's
where I most often use regexes.

Well, it doesn't work if you escape the = with a \, but I'm sure I'm
stating the obvious there and that that behavior is expected. Now that
I'm just escaping the ? in the url I was trying it is working as
expected.
