The ISO 2033:1983 standard ("Coding of machine readable characters (MICR and OCR)")

Magnetic Ink Character Recognition systems. The Japanese standard JIS X 9010:1984 ("Coding of machine readable characters (OCR and MICR)", originally designated JIS C 6229-1984) is closely related.[2]

Character set for OCR-A

The version of the encoding for the

Yen sign at 5C.[2]

Character set for OCR-B

The version of the

ISO-8859-1 codepoints, and the backslash to the ISO-8859-1 codepoint for the Yen sign.[4]

Character set for JIS X 9008 (JIS C 6257)

JIS X 9010 (JIS C 6229) also defines character sets for the JIS X 9008:1981 (formerly JIS C 6257-1981) "hand-printed" OCR font.

curly braces ({, }) and overline (‾)),[5] and kana set (registered as ISO-IR-96 and omitting the East Asian style comma (､) and full stop (｡), the interpunct (･) and the small kana),[6] in addition to a set (registered as ISO-IR-95) containing only the backslash, which is assigned to the same code point as in ISO-IR-93.[7]

The JIS C 6527 font stylises the slash[5] and backslash[7] characters with a doubled appearance. The character names given are "Solidus"[5] and "Reverse Solidus",[7] matching the Unicode character names for the ASCII slash and backslash.[8] However, the Unicode Optical Character Recognition block includes an additional code point for an "OCR Double Backslash" (⑊), although not for a double (forward) slash,[9] although a double slash is available elsewhere, as U+2AFD ⫽ DOUBLE SOLIDUS OPERATOR.

Character set for E-13B

The MICR E-13B font, showing the ISO-IR-98 character repertoire.

The ISO-IR-98 encoding defined by ISO 2033 encodes the character repertoire of the

ISO-IR registration number, and simply e13b.[12]

The digits are preserved in their

bank cheques included in the E13B font is added. The same symbols are available in Unicode in the Optical Character Recognition block
.
