If you are looking into redisigning converters a bit, please take a look
at jdk 1.4 java.nio.charset package. It works on Buffers, so is not
directly usable, but it might be nice to create encoders/decoders so
they could be used later for nio.charset without big change. There is
also one idea I like there - each converter has averageBytesPerChar
float variable, which is a hint for internal allocations.
