[css] [bug] Unicode BOM

[Bjoern H. <der...@gm...>]

Hi,

  CSS::SAC fails to handle the Unicode BOM, i.e. it considers it a part
of an identifier, e.g. if you pass a string like

  "\x{FEFF}a{}"

to parse() it will report a selector consisting of BOM and 'a'. I am not
sure how this should be handled. CSS::SAC does currently not care about
the encoding of the style sheet...
