could not determine encoding for locale "et_EE.UTF-8": codeset is "CPUTF-8" in pg_restore

["Andrus" <kobruleht2@xxxxxx>]

Hi!

Postgres 12 database dump is created in Debian 10 using pg_dump .

Trying to restore it in Windows 10  using

pg_restore --clean --create --if-exists --dbname=postgres --jobs=8 --no-password 
mydb.backup

produces strange message

pg_restore: WARNING:  could not determine encoding for locale "et_EE.UTF-8": 
codeset is "CPUTF-8"

How to fix this ?

Debian and Windows computer have same settings:

Latest Postgres 12  is used
OS and database locales are  Estonian
Database encoding is UTF-8

Andrus.
