I have a problem with Calibre. I converted a persian PDF to EPUB format. But Calibre disarranged the font ! Persian language is in RTL format. Calibre reversed every word as bellow :
ميهمان ====> نامهيم !!!
The correct form is ميهمان
But calibre reversed is and you must read the word from left to right to know what it is !
Do you have any clue for me ?
