The following bug has been logged on the website:
Bug reference: 17194
Logged by: DBA TEAM
Email address: devops@getfareye.com
PostgreSQL version: 12.5
Operating system: Ubuntu 20.04.2 LTS
Description:

We identified that there was an issue with the encoding with UTF8 characters
with pg_output plugin. The data was visible correctly in the database but
while pushing the data through the CDC pipeline there was some distortion
with the Greek letters.
Since pgoutput is a native plugin, kindly let us know any settings or
parameter change that we can do to fix this on postgresql or debezium
side.
FYI:We are using postgresql 12.5 RDS

This is not noticeably different from your previous report, so I don't
know why you'd think you'll get different results. You've still offered
no detail that would let anyone else reproduce the issue, nor any strong
reason to believe that it's a Postgres problem at all.

There is some advice about writing actionable trouble reports at
