Re: [tesseract-ocr] Why combine_lang_model need ommon.unicharset

[Shree Devi Kumar]

Your simple unicharset does not look right. You can make a list of characters needed in a file and create unicharset from it.

unicharset_extractor --output_unicharset cp.unicharset --norm_mode 1  cp.syllables.txt 

combine_lang_model \

--input_unicharset cp.unicharset \

--script_dir ~/langdata \

--output_dir ./ \

--lang cp-recoder

See attached zip file for generated traineddata with and without recoder option.

I use this command follow by a post to create a xx.tessdata

combine_lang_model \
--input_unicharset cp.unicharset \
--script_dir /Users/th/source/langdata \
--output_dir output \
--pass_through_recoder \
--lang cp

and the cp.unicharset is very simple： https://gist.github.com/huhuang03/62391f632d420f7e293e61e878953535

but the shell output is 

Loaded unicharset of size 15 from file mh.unicharset
Setting unichar properties
Setting script properties
Failed to load script unicharset from:/Users/th/source/langdata/ommon.unicharset
Error writing unicharset!!

I can't understand why it look up ommon.unicharset instead of Common.unicharset

And my be I have other wrong?
