KEIS

KEIS is a stateful EBCDIC charset used in Hitachi mainframe systems. KEIS is an acronym for "Kanji processing Extended Information System".

## Encoding structure

Here are the valid ranges of bytes according to its encoding structure.

Byte Range Purpose  | Byte Range in Hexadecimal | Comment

|
|

single byte  | 41-F9  | Includes graphic characters. Does not include unassigned characters nor ISO control characters.
full width space  | 40 40

A1 A1  |
shift to single byte mode  | 0A 41  |
shift to double byte mode  | 0A 42  |
first byte of double byte  | 40, 41-FE  | A1-CF is the basic set. D0-FE is extended set 1. 59-80 is extended set 2. 81-A0 are user defined characters.
Byte 40 is only valid when followed by byte 40.
second byte of double byte  | 40, 41-FE  | 40 is only valid when preceded by byte 40. 0x40 0x40 makes the ideographic space character. Normally only A1-FE is used.
