title_body: Kindle Touch 4th Generation does not render published font correctly I am using Calibre to create an ebook in Urdu language. The language is written from right to left. The whole book is in Unicode and uses UTF-8 encoding. If I open the book in TextEdit on Mac. Mac own fonts such as Helvetica shows the book like this:

  When using default Kindle fonts like Caecilia this is how it looks like
  
  On Kindle with Default Font
  
  However, when I use the published font i.e. the TTF font I have embedded in the ebook. It doesn't join the characters the way it's supposed to for languages like Arabic/Urdu. It shows each letter individually and it looks like:
  
  On Kindle with published font
  
  Am I missing something here or Kindle just can't use these embedded fonts correctly for non-latin languages?
