Find This Character, Please!

OK, if I had hair I would have pulled it out by now. For several months I've been getting this error from BlogCFC, but I can't track the true source to remove the offender:

Script Name: /rss.cfm?mode=full&mode2=cat&catid=9856ECF2-3048-71C2-17879EB46D54D46F Detail: An invalid XML character (Unicode: 0x19) was found in the element content of the document.

I can't find this character anywhere. No clues at all. But, it's playing havoc with some RSS readers, apparently, and loading my inbox. So, anybody have some suggestions how I might find this?

jim hayes's Gravatar It's the control character, so it's likely that it won't have a visual representation in some text editors. You could replace it programatically?
or try pasting it into word and look for something like "???" (your mileage may vary)

I hear you. I've even tried more than a few things. My problem is that the error is coming from some piece of some post to a category with 62 entries, and I don't know which post. I wonder if I can narrow it down with some kind of SQL?

BlogCFC v. 5.8.001 was created by Raymond Camden. Layout inspired by bluerobot.com., with some JQuery thrown in for fun.
