Because whatever you used to "save as" that file has retained or
inserted a BOM (byte order mark, U+FEFF) at the start of the file
before encoding as UTF-8. It's the '\xef\xbb\xbf' at the start of the
file, and also the u'\ufeff' that is giving the gbk codec indigestion.
You can remove it in your script.
