title_body: Calibre fails to unwrap Georgian text I am trying to use the calibre conversion feature to convert ebook written in Georgian from PDF to Mobi. The effect is however very poor. Someone in 10 lines gets unwrapped. I tried to use different unwrapping factors but to no avail. I tested this feature on a Polish book and the effect was satisfactory with default settings.
  
  Important note about Georgian – its script is unicameral. So I suspect that the lack of capital letters at the beginning of the sentences can cause the unwrapping algorithm to fail. But I didn't look at the code, so maybe someone who knows the algorithm better could confirm.
  
  So my questions are:
  
  
  Can it be the unicameral character of the alphabet that causes the problem?
  Can I tweak the algorithm to fix it?
  Is there any other conversion tool that could work for me here.
upvoted_answer: I have checked the source code and it turns out that Calibre doesn't support non-latin script at all. The bug was filed here: https://bugs.launchpad.net/calibre/+bug/1753533 the developer, however, refuses to use Unicode data to recognize alphabetic characters. Mkhedruli was added, but if you want other alphabets to be supported, you either need to manipulate the source code or file another bug.
