Has anyone else seen this code '

I've been experiencing problems in the chat area for technical support for all Apple products. I'm entering text, and then mid sentence, I cannot enter anymore text. I have to get my mouse and click back on the text box to continue to enter text. When I look over the chat transcript they send me after the chat is over, I see this code repeated each time the error occurs. This is the code ' - Today when I was looking up info about an app I had downloaded from the App store on my AppleTV 4th Gen, and I found that code on that webpage also. I think this is a little strange. Here are the screenshots of the two places I found this error code. The first screenshot is from a transcript of an Apple Chat. The second screenshot is from a webpage.
