Hi Christian,

for a benchmark test I have replaced all sun.nio.cs.Surrogate methods in 
sun.nio.cs.ext.EUC_TW with corresponding ones from java.lang.Character.


As result, the overall encoding performance was 10 % worse, so 
java.lang.Character's methods must be much worser.


Can you have a look, if there is a chance to better optimize 
java.lang.Character methods from HotSpot compiler side.



I think you're already looking into this yourself.  -- Christian


  

Yes, correct, I'm trying...
