This is a DATR file.
Try opening it in various text editors like Gedit or Yudit.
Note: with apologies to Arabic speakers, yes the Arabic bits really are just random characters :-)
Vim seems to less painful to work with (but you have to stomach reading from left to right, which is great for a non-Arabic speaker like me, but I imagine not so fun if you can read Arabic and have to fight your instincts)
