If the intent is to just sniff and parse the file accordingly, I get
enough of these junk UTF-8 BOMs at $DAY_JOB that I've had to create
utility-openers much like Steven is doing here.  It's particularly
problematic for me in combination with csv.DictReader, where I go
looking for $COLUMN_NAME and get KeyError exceptions because it wants
me to ask for $UTF_BOM+$COLUMN_NAME for the first column.
