Thanks Rudi, this is a step forward, but there is still some problems. In Farsi or Arabic, most of the words are combined of letters stick together, but now, it shows them as a separate letters. For example it shows این (this) as a three separate letters ن ی ا
or below sentence sample:
این یک تست است (this is a test)
It shows like below:
ت س ا ت س ت ک ی ن ی ا
also shows them LTR which should be RTL

There was no problem with tcpdf library.
