Multibyte Characters Become Square Box on Java Based GUI applications (DBCA, NETCA, ASMCA and OUI) (Doc ID 2658495.1)

Last updated on SEPTEMBER 30, 2020

Applies to:

Oracle Database - Enterprise Edition - Version and later
Linux x86-64
Linux x86-64 on Oracle Public Cloud


After successful installation of Oracle Database using Oracle Database RPM using yum, all of multi byte characters are replaced by square box when Database Configuration Assistant (DBCA) are invoked.


LANG environment variable for Oracle software owner (typically, oracle) was changed to any other multi byte locales(e.g. ja_JP.UTF-8) from single byte locales(e.g. en_US.UTF-8).
