   In my testing, it appears that IE 7 and Firefox 2 do treat GBK as  
an equivalent of GB2312, but this cannot be said about GB18030. In  
particular, 0x80 and 0xA2E3 are treated differently.


   What differences are you seeing between Firefox and WebKit? It  
seems that the behavior may be a bit more tricky than just treating  
all encodings from GBK family as GB18030.
