Displaying a Percent Sign (%) in a SCOM Event Description

I googled around a bit and discovered that the SCOM's "Description" field in the "Details" pane is actually rendered in HTML. Handy info, that, but it didn't help me get a percent sign rendered.

I ended up trying every contrivance you can imagine to try to make it happen -- all to no avail.

Ultimately, the magic that worked: "%%". Go figure.
