It is a surprise to see that the String.charAt is way faster than the
char index access...I had
the assumption that the array access is faster when considering to move
the mappable table
from the String storage to a simple 256 length char for both
singlebyte and doublebyte charsets.
Ulf, Martin and I were (will continue to, hopely) working on a project
to improve the performance
of the charset implementation, your contribution will definitely
