invalid multibyte character for locale

Hi,

Recently I restored a database from 7.4.1 (RHAS3.0) to 8.0.3 (RHAS4.0),
and now we are running into locale issues:

[22:03] WARN SECUserDAO () - Problem retrieving user by username.
org.sourceforge.jxutil.sql.I18nSQLException: sqlError[invalid multibyte
character for locale]

...

ERROR: invalid multibyte character for locale

HINT: The server's LC_CTYPE locale is probably incompatible with the
database e

ncoding.

ERROR: invalid multibyte character for locale

HINT: The server's LC_CTYPE locale is probably incompatible with the
database e

ncoding.

The original database is in UNICODE, and so is the new database, on
8.0.3. I am reading the pg doc about locale and character set encoding,
but with the source and target database having been created with same
encoding, I am not sure why the LC_CTYPE may not be compatible with
UNICODE.

Any help is appreciated.

Thanks,
Anjan
