       combine_lang_model - generate starter traineddata


       combine_lang_model --input_unicharset filename --script_dir dirname --output_dir rootdir
       --lang lang [--lang_is_rtl] [pass_through_recoder] [--words file --puncs file --numbers


       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


       -l lang
           The language to use. Tesseract uses 3-character ISO 639-2 language codes. (See

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

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

       --pass_through_recoder BOOL
           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_str STRING
           An arbitrary version label to add to traineddata file (type:string default:)

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

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

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


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