Modify character set in Oracle Express

The default database character set is al32utf8.
The company uses the zhs16gbk character set, so the character set is changed using the following method:

Sqlplus sys_name/sys_password as sysdba shutdown immediate; Startup Mount alter system enable restricted session; Alter database open; Alter database character set internal_use zhs16gbk; shutdown immediate startup

The character set is changed, and the appex is garbled.

Solution: Modify ie-Internet option-language-add English (U.S.), and then move the English language to the first option to change to the English version of apex.
