block includes those symbolic
characters of the OCR-A
character set that do not correspond to ASCII
characters. OCR-A consists of carefully drawn uppercase A to Z, plus a few other specialty signs. OCR-B
adds lowercase and a few more punctuation marks.
It also contains magnetic ink character recognition (MICR) symbols used in check processing. The MICR character set E-13B, used primarily in the USA and Canada, consists of the numbers 0-9 and a few other special character that you see printed at the bottom of most checks. Note that these are printed with a special magnetic ink, and so are read magnetically, rather than optically. The font is based on a grid of 7 by 11 squares, and filled to make them more distinct to the reader.
The MICR character set CMC-7, designed in France and used in Europe, also contains the letters A-Z. Each character is made up of seven vertical lines, each line either thick or thin. Each line has a length and position to make it resemble the letter in question.
Note that Unicode does not deal with display issues, and so does not re-encode the regular ASCII characters.
Both of these sets of symbols are specified in ISO 2033
