[bug?] on one site - Exception: 'utf-8' codec can't encode character '\ud83d' - surrogates not allowed

**Describe the bug**
When checking for changes, changedetection reports the following error:

`Exception: 'utf-8' codec can't encode character '\ud83d' in position 419201: surrogates not allowed`. From what I gather, "\ud83d" is an emoji, yet I can't find one on the site I'm monitoring. I also check the site's code and couldn't find anything.

This is what the log says:

```

**Expected behavior**
The check should complete without errors.

**Desktop (please complete the following information):**
- OS: Unraid

**Additional context**
Interestingly enough, when going through the browser steps myself, no error is reported and a screenshot of the site is saved. Removing the browser steps does not prevent the error from appearing though.
