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 ?
Regrettably I can't compare your results against the results from day before (without the tweaks suggested from my side), as it seems you have used different algorithm. :-(

I simply ran the test case TestEUCTW attached in the test case, set the iteration set to 200, run with BMP characters only, supplementary characters only and mixed.

Though this is not a real benchmark, the data does say something.
