I'm on 5.21. The upgrade was done by someone at your company--in fact, I think you did it. The guy who performed the upgrade was just a little north of me (I'm in Baltimore)
I don't know why you don't understand the problem. I have posted clear examples above of where " and & are being turned into some kind of ASCII gibberish. For instance this photo
shows the following text: 30" Bluefish weighing 6 1/2#'s caught at LIP on a White/SkyBlue Gotcha Plug! 30"
should read 30"
Try uploading a photo and typing " or & and you'll see what happens.
