Gluster users - Mar 2020 - Geo-Replication - Does not finish syncing - Codification Error

Hi,
I am having a problem syncing two volumes using Geo-Replication.
The entire certification and activation process works correctly. But when 
synchronization starts it stays almost at the beginning of the first files and 
never ends the job.

Checking the Glusterfs logs I find this error:

UnicodeEncodeError: 'utf-8' codec can't encode character
'\udcba' in position
115: surrogates not allowed

Searching the internet a bit I have found that the error is due to a character 
encoding problem. The typical diamond with the question mark.
I have had to perform a conversion of the files with this utility.

convmv -r -f cp1252 -t utf-8 /folder_of_share/ --notest

Now this is a temporary fix, since it does not guarantee that in the future 
someone will copy another file or folder with a different format than utf-8 and 
find that it stops synchronizing the rest of the contents to the slave.

Does anyone know how this problem can be corrected?

Thank you.
