Overview
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.
