Smile [Q] How to Install Arabic System font on S3 (T-MOBILE)

Hi,

Before I ask the question I would like to apologize, in case this is not the appropriate location for this thread. I tried to search via XDA search for my question but I don't think I found the answer, but maybe have a sort of an idea about it.

Basically my question is:

My friend gave me a T-Mobile Samsung S3 (SGH-T999, 4.1.1), and he was asking me is it possible to get Arabic as the system font instead of the default English?

From what I did via my research. I discovered that I need to root and install a custom rom, if I am not mistaken. Is this the only way to do this, or is there any other method of doing so?

Furthermore, can I be linked to a tutorial, or step by step instruction on rooting the device on this firmware.

I appreciate everyones' assistance.

Thank You!
