Hi Janusz, Tesseract 4 uses tesseract-ocr-deu and tesseract-ocr-script-frak. Tesseract 3 uses tesseract-ocr-deu-frak
I am worried about confusing users. If we include both sets of language data in Debian, there will a huge number of choices, and some users might feel overwhelmed. However, Alexander thinks it could work with careful package naming, like this: https://mentors.debian.net/package/tesseract-lang-legacy I am also a little worried about the support costs of exposing lots of users to the legacy engine. It will make it harder to remove the legacy engine completely from future Tesseract. Especially if other Debian packages start to have dependencies on it. Also bug reports against the legacy engine will not get much attention from upstream. We'll discuss this with upstream, but in the meantime I have a question for you: What is your best guess for how many people are like you, and want to use the Tesseract 3 engine in Debian? Thanks, Jeff
