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.
