Updated the webrev with some "final tweak".

http://cr.openjdk.java.net/~sherman/68317946229811/webrev (1)change the MSB to < 0x80 as Ulf suggested, hope it faster, but it at lease saved one field from the class file:-) (2)tweak the encoder code a little to encode supplementary character only after BMP character encoding failed, as commented in the code, it boots the BMP encoding about 10% on the price of supplementary character, but something worth doing.

I think, this was good idea !

(3)tweak the initC2B code a little to make it a little faster (to avoid the n * segSize)

Also good :-)

Hope this is really a final one:-) the performance data looks good enough for me, yesterday and today's tweak seems to be helpful, thanks Ulf!

Could you share the new performance data ?

After we are done with this one, please keep doing the real "ibm charset rewrite":-)

Tomorrow..... :-)
