I believe I have changed the encoding of a file I created(not sure), and when I changed it back to UTC-8 it left some invisible spaces. In between letters I need to press the backspace multiple times in order to delete a letter. When I Typeset I get this message for all words basically:
Textline contains invalid character e@^^m^^@g^^@l.. and goes on and on with @^^ in between letters. Is there any way I can delete all of them?
My other solution is a painful RE-write of the whole paper which is going to take at least 3-4 hours.
