Arabic (ar) support

Description:

I noticed that when I use langman artisan command to make an Arabic translation it aborts without adding the translation and without carrying-on to the other languages.

As an overall observation, Arabic is not supported every command (sync, missing, trans...) throws errors when Arabic is around.

Steps to reproduce:

add an Arabic translation to to resources/lang/ar folder and use langman.
