Arabic font displaying incorrectly on receipt

In Oracle Retail Point of service we have functionality called e-receipt which is used to send the receipt to customer’s email-id(our code will convert the ordinary receipt into PDF document and same has been sent to the customer).

Our client’s request to incorporated the Arabic text along with English text in e-receipt functionality. We are able to print the proper receipt at XXXX printer. But we are facing the issue in e-receipt from long time ,  we are writing the both Arabic & English receipt data into pdf format through a java program , when we open pdf both Arabic and English  character are displaying as overlapping and not proper alignment , words are overlapped, text becomes jumbled and has the different meaning which is not related as same as printed one.

Please response me earliest possible in this mail.
