No, an empty file has no data; the size is 0. You must have saved a
text file in Windows that added a byte order mark (BOM). Windows adds
a BOM for UTF-8 and UTF-16 ('Unicode') files. It sounds silly to have
a BOM for UTF-8, which can't have a little endian or big endian byte
order, but it's there to distinguish UTF-8 from 8-bit ANSI (e.g.
Windows 1252).
