Gujarati, Hindi and Sanskrit Language OCR not working

[vikithakar]

Description of Issue

After building Papermerge with Gujarati, Hindi and Sanskrit Language support, when you upload and run OCR on files, it churns out OCR text which is not correct. I think the tesseract-ocr is consistent with the text output it gives for the file, but it seems like papermerge does not have fonts or Character Sets to display the translations in the OCR text language.

Build Details

Dockerfile to add tesseract-ocr to papermerge

FROM papermerge/papermerge:3.0.2
RUN apt install tesseract-ocr-hin tesseract-ocr-guj tesseract-ocr-san -y

Info:

• Papermerge Version 3.0.2

In order to make this work, I need to include Gujarati, Hindi and Sanskrit codes here and here. For the second list, I need respective language written in original language; for example fra in French is "Français"; ell in Greek is "Ελληνικά".

Could you please provide original writing of the language name for Gujarati, Hindi and Sanskrit ?

• guj in Gujrati is "..." ?
• hin in Hindi is "..." ?
• san in "Sanskrit is "..." ?

PR for adding above mentioned languages.

Change will be available in 3.0.3 release

Note that you will need to build your image as before. However, when you will start papermerge don't forget to add PAPERMERGE__OCR__DEFAULT_LANGUAGE variable so that when you import docs they will be OCRed in "default OCR" language.

In ticket's screenshot you've uploaded you can see that document was OCRed with OCR language being set "German" (deu code corresponds to German language). That's why those strange characters.
