Fonts
There are two major MICR fonts in use: E-13B and CMC-7. E-13B has a 14 character set, while CMC-7 has 15 - the 10 numeric characters, plus control characters.
The MICR E-13B font is the standard in the United States, Canada, United Kingdom, Australia and other countries. (The "13" in the font's name refers to the 0.013 inch grid used to design it.) Besides decimal digits it also contains the following symbols: ⑆ (transit: used to delimit a bank branch routing transit number), ⑇ (amount: used to delimit a transaction amount), ⑈ (on-us: used to delimit a customer account number), and ⑉ (dash: used to delimit parts of numbers, e. g., routing numbers or account numbers).
Major European countries, including France and Italy, use the CMC-7 font developed by Groupe Bull in 1957.
