From 5463a2b0566b34b9e3847db9ceb1ef1d2a6004fc Mon Sep 17 00:00:00 2001 From: Baptiste Coudurier Date: Wed, 21 Mar 2012 14:18:16 -0700 Subject: [PATCH] movdec: handle 0x7fff langcode as macintosh per the specs The correct point that seperates ISO and MAC language codes is 0x400 according to the current QT spec. Old QT specs did not list where this seperation is but apparently only defined the meaning of the first 137.
