 ## File Format
 
 Files should be saved with Unicode (UTF-8) encoding. The BOM should _not_ be used. Unlike UTF-16 and UTF-32, there's no byte order to indicate in a UTF-8 encoded file, and the BOM can have a negative side effect in PHP of sending output, preventing the application from being able to set its own headers. Unix line endings should be used (LF).
