Subheadings
The Optical Character Recognition block has three informal subheadings (groupings) within its character collection: OCR-A, MICR, and OCR.[3]
OCR-A
The OCR-A subheading contains six characters taken from the OCR-A font described in the ISO 1073-1:1976 standard: U+2440 ⑀ ocr hook, U+2441 ⑁ ocr chair, U+2442 ⑂ ocr fork, U+2443 ⑃ ocr inverted fork, U+2444 ⑄ ocr belt buckle, and U+2445 ⑅ ocr bow tie. The OCR bow tie is given the informative alias "unique asterisk".
MICR
The MICR subheading contains four characters standardized in the ISO 1004:1995 standard, from the magnetic ink character recognition E-13B font: U+2446 ⑆ ocr branch bank identification, U+2447 ⑇ ocr amount of check, U+2448 ⑈ ocr dash, and U+2449 ⑉ ocr customer account number. The latter two characters are misnamed but have correct normative aliases: U+2448 ⑈ is MICR ON US SYMBOL, and U+2449 ⑉ is MICR DASH SYMBOL (the standard notes that "the Unicode character names include several misnomers"). All four characters have informative aliases: "transit", "amount", "on us", and "dash" respectively.
OCR
The OCR subheading consists of a single character: U+244A ⑊ ocr double backslash.
