combine_lang_model - generate starter traineddata

       The Tesseract OCR engine was written by Ray Smith and his research groups at Hewlett Packard (1985-1995)
       and Google (2006-2018).

combine_lang_model(1) generates a starter traineddata file that can be used to train an LSTM-based neural
       network model. It takes as input a unicharset and an optional set of wordlists. It eliminates the need to
       run set_unicharset_properties(1), wordlist2dawg(1), some non-existent binary to generate the recoder
       (unicode compressor), and finally combine_tessdata(1).

combine_lang_model(1) was first made available for tesseract4.00.00alpha.

       combine_lang_model - generate starter traineddata

--langlang
           The language to use. Tesseract uses 3-character ISO 639-2 language codes. (See LANGUAGES)

       --script_dirPATH
           Directory name for input script unicharsets. It should point to the location of langdata (github
           repo) directory. (type:string default:)

       --input_unicharsetFILE
           Unicharset to complete and use in encoding. It can be a hand-created file with incomplete fields. Its
           basic and script properties will be set before it is used. (type:string default:)

       --lang_is_rtlBOOL
           True if language being processed is written right-to-left (eg Arabic/Hebrew). (type:bool
           default:false)

       --pass_through_recoderBOOL
           If true, the recoder is a simple pass-through of the unicharset. Otherwise, potentially a compression
           of it by encoding Hangul in Jamos, decomposing multi-unicode symbols into sequences of unicodes, and
           encoding Han using the data in the radical_table_data, which must be the content of the file:
           langdata/radical-stroke.txt. (type:bool default:false)

       --version_strSTRING
           An arbitrary version label to add to traineddata file (type:string default:)

       --wordsFILE
           (Optional) File listing words to use for the system dictionary (type:string default:)

       --numbersFILE
           (Optional) File listing number patterns (type:string default:)

       --puncsFILE
           (Optional) File listing punctuation patterns. The words/puncs/numbers lists may be all empty. If any
           are non-empty then puncs must be non-empty. (type:string default:)

       --output_dirPATH
           Root directory for output files. Output files will be written to <output_dir>/<lang>/<lang>.*
           (type:string default:)
