Try changing your encoding, see the image:

Answer 2

That's a problem related to BOM (Byte Order Mark) character. Eclipse doesn't allow this character.

Just copy paste the same content to a Notepad++ editor,
it shows the "LS" with black background. Have deleted the "LS" content and 
have copy the same content from notepad++ to java file, it works fine.
