Engine Language Changed

Hello , I am getting a little bit problem in unity 5 that's making me sick , all other things are working great but just that .. My inner engine language changed to some other language automatically after some seconds , First it works with English like always but than suddenly the text i write changed to question mark cause it can't able to understand that language . But when i save the scene it show the other language called Hindi or i don't know if it's something else but it looks very related to Hindi . Here are some pics to show .
