Which languages are supported in pdfOCR?

Since pdfOCR relies on Tesseract 4.1, you can always retrieve the latest language (+130!) data models and scripts (+35) on their GitHub repo.

If you require fonts to render advanced typography on a separate layer of your OCR document, please check out pdfCalligraph.
