working with none english text in firefox extension (addon)

Question

This is the code that I have in javascript file inside my addon:

 function ShotText() {
      var inputString = "שלום"; //Hebrew letters
      alert(inputString);             
}

When I run this function using addon I get this:

But if I run the same code without addon (regular javascript function), I get this:

Where is the problem?

Maybe I need to set encoding somewhere inside the extension?

Answer 1
