Introduction

Optical Character Recognition technology, OCR, came into use in the 1960s, and some specialized OCR fonts

were designed at the time. In 1976 two such fonts were formally standardized by ISO, designated OCR-A and

OCR-B, in the standard ISO 1073 parts I and II, respectively.

ISO 1073 was developed by the ISO Technical Committee ISO/TC97, Computers and information processing. At

the creation of ISO/IEC JTC 1, responsibility for ISO 1073 was transferred to JTC 1/SC 2, Coded character sets.

In order to enlarge the set of characters covered by the standard, especially with special letters used in European-

origin languages, a revision of the standard was initiated in 1994 by JTC 1/SC 2, and progressed through three

consecutive Committee Drafts. Since however testing of the proposed character set extensions could not be ac-

complished, the JTC 1/SC 2 revision was discontinued in 1999.

With the introduction of the Euro sign a need – primarily European – to add that character to the OCR-B set was

recognized. CEN/TC304 therefore decided to develop an OCR-B glyph image shape for the character, verify its

recognition properties, and include it in a European version of the OCR-B standard; see CEN/TC304 reports refer-

enced in the Bibliography. The decided-on glyph image shape is specified in Annex A.

For reasons of continuity, and also to facilitate possible future CEN – ISO/IEC cooperation on OCR-B, it was de-

cided to use the current ISO text with only the necessary minimum of changes as a basis for the CEN standard,

even though the ISO text was developed in an OCR-technology situation rather different from the one existing

when this CEN standard is published. In particular, the ISO standard text's division into clauses was kept as far as

possible, although some restructuring might have been desirable.

A description of the main differences between this European Standard and ISO 1073/II is given in Annex B. Gen-

eral information on the implementation of the OCR-B shapes, taken from ISO 1073/II, has been included in An-

nex C.

In connection with the verification of the recognition properties of the Euro sign, some limited verification was also

done on special letters identified during the JTC 1/SC 2 revision work as needed in OCR-B. The extent of this veri-

fication is not sufficient for the inclusion of the letters in the OCR-B repertoire at present, but the issue is described

in Annex D, as a basis for possible future inclusion work.

9.4 Subset 4: Options subset

This subset applies to sizes I and IV in constant-strokewidth font and to size I in letterpress font. It contains 8 capital

and 5 small national letters, 4 diacritical marks and 3 further glyph images.

Images from this subset shall be used only in conjunction with subset 3. A printing or OCR reading device may gen-

erate/recognize any of the images of this subset. The images generated/recognized by the device shall be listed in

the claim of conformance (see clause 2).
