===MICR===

The MICR subheading contains four punctuation characters standardizedfor in[[bank thecheque]] ISO 1004:1995 standardidentifiers, taken from the [[magnetic ink character recognition]] E-13B font (codified in the ISO 1004:1995 standard): {{unichar|2446|OCR BRANCH BANK IDENTIFICATION}}, {{unichar|2447|OCR AMOUNT OF CHECK}}, {{unichar|2448|OCR DASH}}, and {{unichar|2449|OCR CUSTOMER ACCOUNT NUMBER}}.

The MICR subheading contains four characters standardized in the ISO 1004:1995 standard, from the [[magnetic ink character recognition]] E-13B font: {{unichar|2446|OCR BRANCH BANK IDENTIFICATION}}, {{unichar|2447|OCR AMOUNT OF CHECK}}, {{unichar|2448|OCR DASH}}, and {{unichar|2449|OCR CUSTOMER ACCOUNT NUMBER}}.

The latter two characters are misnamed (their names were inadvertently switched when they were named in [[ISO/IEC 10646:1993]]).<ref>{{citation|mode=cs1 |url=https://www.unicode.org/wg2/docs/n4103.pdf |page=29 |section=T.3.

These symbols had previously been encoded by the ISO-IR-98 encoding defined by [[ISO 2033]]:1983, in which they were simply named {{sc|SYMBOL ONE}} through {{sc|SYMBOL FOUR}}.<ref>{{cite web |url=https://www.itscj.ipsj.or.jp/iso-ir/098.pdf |title=ISO-IR-98: A set of 14 graphic characters of the E13B font. |author=ISO/TC97/SC2 |author-link=ISO/IEC JTC 1/SC 2#History |publisher=ITSCJ/[[Information Processing Society of Japan|IPSJ]] |date=1985-08-01}}</ref> All four characters have informative aliases in the Unicode charts: "transit", "amount", "on us", and "dash" respectively.

All four characters have informative aliases: "transit", "amount", "on us", and "dash" respectively.
