Error while scanning my root folder: 'utf-8' codec can't encode characters...

[a375702]

I got this error in the log:
directory_watcher.py : scan_photos : 237 : ERROR : 'utf-8' codec can't encode characters in position 37-42: surrogates not allowed

How can I find out which folder is causing issues? How to fix this?

You have a folder with a encoding that is not utf-8.
You can try scanning only part of the folders to narrow it down, there is no code to return what folder is causing it.

Its happening because of this:

Perhaps there is a way to replace it. It looks like its only a print
