So I went to back up my website, since it had been awhile since I last did. So I sent to tools, export, and downloaded the file like I normally do. When I opened the file there was an error at the top(in red) that said this:

This page contains the following errors:

error on line 6062 at column 29: Input is not proper UTF-8, indicate encoding ! Bytes: 0x13 0x0C 0x13 0x0C

Below is a rendering of the page up to the first error.

I attached an image below as well.

The back up does seem to have a lot of my website stuff on it, but I am concerned, based on the error message, that not all of my website is backed up.

Am I correct on that assumption? If so, how do I fix this?

Thx for any help bc I am not a coder by any means.
