PW URL checker rejects valid URL

[modifiedcontent]

I'm trying to use an RSS feed with an unusual format that works fine in browsers, but PW's field checker keeps rejecting it. I've tried several variations of this:

... /__rss/website-scheduled-content.xml?input={"sectionAlias":"process"}

... /__rss/website-scheduled-content.xml?input=%7B%22sectionAlias%22%3A%22process%22%7D

Any ideas how to get this through?

Edit: Nevermind, I see the HTML Entity Encoder on the field has an option to allow single/double quote characters. That fixed it.
