(you mean "\xef", not "\xref")

This is a byte-order-mark (BOM), which you can read about at [1].  In
this case, it denotes the file as UTF-8 encoded.  Certain programs
insert these, though it's more important with UTF-16 or UTF-32
encodings where the byte-order and endian'ness actually matters.  I
believe Notepad and Visual Studio on Win32 were both offenders when
it came to inserting unbidden BOMs.
