Sorry, my faint memory says that something like that happened on
backup label but I don't recall that clearly.

pg_basebackup can set the LABEL field in the file and the string fed
to the command's "-l" option is copied to there as-is (that is,
getting no conversion), as far as client encoding is valid as server
encoding. (since database encoding of walsender is always SQL_ASCII)
I'm not sure it is the expected behavior.
