Hi Phil,

I ran Font2DTest and SwingSet2 with the patch, and they look good.

Thanks, Johnny Chen

Supplementary chars are DOA in the OS X port since the mapper code there is ignorant of them, doing such things as down-casting an int code point to a char before doing the lookup and storing the first char of a surrogate pair as being the map key, not the decoded supplementary char. Interestingly the key to the map was of type integer so that part I didn't have to change. I've run through Font2DTest and SwingSet with this patch. Since it touches a key part of the code if there's bugs I'd expect them to show up there. I didn't see any problems and it improves the supplementary char support. I expect to back port this to 7u40 since its clearly a major issue, but there's not much time for it to bake in 8 first, so please try it out (if you can). -phil.
