If I upload php files that are encoded in UTF-8, instead of ANSI, it creates problems with "headers already sent" on the server.
vi shows {feff} at the start and nano does not show the \ at the start. When I remove the {feff} manually in vi, it works fine. But after every new FTP upload, this is added again.
This also happens to .html and .ctp files, but so far never has been a problem.
