ISO 646-JP OCR-B
From Just Solve the File Format Problem
ISO 646-JP OCR-B (646-JP OCR-B, ISO IR-92, IR-92) is one of several 7-bit character encodings in the ISO/IEC 646 series which are national variants, replacing some of the ASCII characters with other characters suitable for particular languages. This one is aimed at the Japanese market, in the version specifically for use with the OCR-B font for optical character recognition. It appears to have the exact same characters in the exact same positions as the regular ISO 646-JP encoding, so the purpose of having a separate encoding for it is unclear.
