No ampersands in FeedFlares?

UPDATE: I am an idiot. Here is the solution.

Bummer.

I seem to have run into a limitation/bug in FeedBurner’s FeedFlare system: for some reason, a FeedFlare that contains an ampersand (&) is not considered valid. When I try to add one as a Personal Flare, I get this error:

We could not find a valid FeedFlare file at that location.

The FeedFlare I was creating takes two parameters—the URL of the feed as well as the URL of the individual item—hence the need for an ampersand. Here’s an example:

http://rossbelmont.com/printerfriendly/display?↵
feedUrl=http://feeds.feedburner.com/Arbited↵
&itemUrl=http://rossbelmont.com/blog/articles/↵
2006/05/10/restart-rails-on-a-shared-host

The purpose of the FeedFlare is to generate a printer-friendly view of a certain item in the feed. The FeedFlare itself has this URL in it:

http://rossbelmont.com/printerfriendly/display?↵
feedUrl=${feedUrl}&itemUrl=${link}

And again, if I take the ampersand out, it validates without any isses. But, unfortunately, if I do that I can’t have more than one parameter in the query string.

I also tried to URL encode that link to see if that would help, but that returns an error when you actually click the generated link because the ${feedUrl} and ${link} tokens are not interpreted correctly.

So, if anyone has an idea for how to get around this, I’m all ears.
