Comment (by guest):

 Please note, that according to
 http://en.wikipedia.org/wiki/Byte_Order_Mark the character U+FEFF is
 considered a BOM only if it appears as the first character of a file. In
 the context of UTF-8 it simply serves to identify the encoding. So there's
 no need to lex it as space, only to ignore it as the first character of a
 source file. Thanks.
