The database must be created using Unicode Transformation Format UTF-8 encoding (character set). Oracle supports the following character sets with UTF-8 encoding:
AL32UTF8 (UTF-8 encoding for ASCII platforms)
UTF8 (backward-compatible encoding for Oracle)
UTFE (UTF-8 encoding for EBCDIC platforms)
Note: | The UTF-8 character set must be applied to the client and to the Oracle database. |
