This bug or issue have been in minecraft since other languages were added
arabic language in minecraft is like ا ل ل غ ة ا ل ع ر ب ي ة
and it's suppose to be اللغة العربية
there is a lot of people in youtube that have corrected it.
and the first guy that did was in reddit
Link: http://www.reddit.com/r/Minecraft/comments/u33p8/about_fixing_the_arabic_language/
and he has been fixing the language every update.
but we never see an offical fix from mojang itself
i hope this get fixed soon
Thank you 🙂
