NAME

       unicharset_extractor - Reads box or plain text files to extract the unicharset.

SYNOPSIS

       unicharset_extractor [--output_unicharset filename] [--norm_mode mode] box_or_text_file
       [...]

       Where mode means: 1=combine graphemes (use for Latin and other simple scripts) 2=split
       graphemes (use for Indic/Khmer/Myanmar) 3=pure unicode (use for
       Arabic/Hebrew/Thai/Tibetan)

DESCRIPTION

       Tesseract needs to know the set of possible characters it can output. To generate the
       unicharset data file, use the unicharset_extractor program on training pages bounding box
       files or a plain text file:

           unicharset_extractor fontfile_1.box fontfile_2.box ...

       The unicharset will be put into the file ./unicharset if no output filename is provided.

       NOTE Use the appropriate norm_mode based on the language.
