[whatwg] Turkish encodings: ISO 8859-9 < CP1254

[Øistein E. Andersen]

As suggested earlier, ISO 8859-9 is a proper subset of CP1254,
and IE7 always uses the superset.  [Actually, the name shown
in the menu varies -- Turkish (ISO) v. Turkish (Windows) --, but
the underlying encoding vector appears to be the same.]

Test pages (identical data, different Charset headers):

        <http://coq.no/X/testturk-win.php>
        <http://coq.no/X/testturk-iso.php>

HTML5 should probably encourage this given that this is analoguous
to ISO-8859-1/CP1252 and Thai encodings.
