I have a few invisible characters (�) that appear at the end of a javascript document that cause the "illegal character" error in FF or Chrome. I saw different topics about this error, but nothing works for me, and i can't see anything wrong in my document (displaying invisible characters, open it with a hexadecimal editor). This is just driving me crazy. I use Vagrant with a nginx web server. The document looks clear in the server too (vi + :set list).
Plus, when I get back a clear document from my Git repository, everything works(normal). But each time I want to edit it (like create a new variable at the top of document), I got this error again.
If someone can helps me, thank you.
