Flashed my Android and now I can't display arabic, Hebrew I followed this tuto to flash a zip to my phone (S3 mini - Android 4.4.4 )  using flashfire to show the new emojis. All seems to work well though I noticed Arabic and many other languages are not displayed I only see boxes.

Is there any way to fix it knowing that I skipped the backup step.
I fixed the issue all you need is to flash the firmware ROM. I was using a custom ROM so I used CWM recovery to install it. Here's a link that could help but DON'T wipe data/reset factory, otherwise you will lose all your data.
