Subheadings

The Optical Character Recognition block has three informal subheadings (groupings) within its character collection: OCR-A, MICR, and OCR.[1]

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.
