This is a special kufi (banaei) font which performs like a Tahriri or Nastaliq font!
You write with this font and the letters goes up the baseline as you can see in the pictures. It supports Persian/Arabic and it is one of my personal favourite projects so far. Hope you like it too.
And if you want to stop the moving up the baseline feature everywhere in the text you can just press ـ or Tatweel (Usually Ctrl + J or Ctrl + ـ on Windows) and you're done :)
