Custom words combining letters + digits

[David Novak]

Hello,

I have a custom list of words that I'd like to add to (or practically substitute for) the default word list in my language. Some of these words combine letters & digits & punctuation e.g.

0.5KG

0.5L

1.1L

1.25KG

108G

4DOG

I'm using tesseract 4.0. My approach so far:

 - unpack lang.traineddata

 - create cus.lstm-word-dawg  (either just from my wordlist or as combination of standard language list + my list)

 - create new .traineddata from cus.lstm cus.lstm-recoder cus.lstm-unicharset cus.lstm-word-dawg cus.traineddata

It has practically no effect... Often, a word that actually is in the list is recognized wrongly as some string that is not in the list.

I have tried to add these words using --user-words <mylist.txt>: no effect, or the same as my approach

I have tried -c language_model_penalty_non_dict_word=1.0  (I thought it would limit the output to words in cus.lstm-word-dawg): no effect

I'm out of ideas after two weeks of trying. Any tips, please?

Thanks

--user-words does not currently work in tesseract4.
