This European Standard defines a set of glyph images
designated OCR-B, intended primarily for use
in Optical Character Recognition (OCR) applications,
but suitable also for visual, i.e. human,
reading. It does not relate any coding scheme with
these images (see clause 5).
This European Standard is based on the ISO standard
1073 part II. It differs from that standard in
extending normatively the set of glyph images with
the Euro currency sign; but also in deleting some
glyphs not relevant in present-day OCR processing.
It further adds information on a number of glyph images
corresponding to characters specific to some
European-origin languages.
NOTE In ISO 1073 Part II the term "character" is
used not only in its strict sense, but also to mean the
printed images used for their visual, i.e. printed, representations.
In this European Standard the term "glyph
image" is used in the latter sense.
This European Standard contains information on
nominal dimensions for the glyph images. Tolerances,
printing quality and other characteristics of
the formats needed to satisfy interchange requirements
are covered in other standards (see clause
3).
The glyph image set contains 117 glyph images
comprising digits, capital and small letters, diacritical
marks, and symbols. It also contains a definition for
SPACE.
The diacritical marks are designed for combination
with small letters to produce composite glyph images
complementing the basic image repertoire.
