ABBYY FineReader 12 User’s Guide

9. Teach the program to read new characters and ligatures.

A ligature is a combination of two or three characters that are "glued together" (for example, fi, fl,

ffi, etc.) and are difficult for the program to separate. In fact, better results can be obtained by

treating them as single compound characters.

Note: Words printed in bold or italic type in your text or words in superscript/subscript may be

retained in the recognized text by selecting the corresponding options under Effects.

To go back to a previously trained character, click the Back button. The frame will jump to its

previous location and the latest trained "character image – keyboard character" correspondence will

be removed from the pattern. The Back button navigates between characters of one word and will

not navigate between words.

Important!

 You can only train ABBYY FineReader to read the characters included in the alphabet of the

recognition language. To train the program to read characters that cannot be entered from

the keyboard, use a combination of two characters to denote these non–existent characters

or copy the desired character from the Insert Character dialog box (click to open the

dialog box).

 Each pattern may contain up to 1,000 new characters. However, avoid creating too many

ligatures, as this may adversely affect OCR quality.
