KANJIEBCDIC5035_0I - Teradata Tools and Utilities

The character set on the database named KANJIEBCDIC5035_0I is intended as an extended EBCDIC character set consisting of both one and two-bytes per character. Architecturally, the EBCDIC encoding scheme consists of 256 possible values (codepoints) represented as hexadecimal values in the range X'00' to X'FF'.

To support more than 256 codepoints, the EBCDIC encoding scheme is extended by defining the Shift-out control character to switch from one byte per character to two bytes per character until the Shift-in control character is encountered. The first byte of codepoints between the Shift-out and Shift-in control characters is always between X'41' and X'FE'. Currently, the second byte is also between X'41' and X'FE'. The X'4040' codepoint is defined as the Double-byte Space character. No double-byte control characters exist. The double-byte characters are not described.

The database rejects character data containing any single or double byte reserved codepoint and will not identify which invalid codepoint was present.

While graphic characters adhere to the standard definition for IBM code page 01027, the control characters and Eight Ones character do not because all common control characters are not present, and the Eight Ones character is not included.

The database defines the Overline character for KANJIEBCDIC5026_0I, KANJIEBCDIC5035_0I, Katakana, and SCHEBCDIC935_2IJ differently than for the other character sets. If this character is sent to the database using a character set in one group but received from the database using a character set in the other group, the codepoint will change.

No special processing is performed by the database for control characters, except for Shift Out and Shift In, which switch to and from double-byte codepoints.
