Even for UT-16 I believe for the high planes of unicode the characters have to be encoded using pairs of chars, so it's not quite a simple write of chars but pretty close.

But in any case, simple comparisons and bitwise operations are fast. I doubt this is the reason why the encoding is slow.

My bet, as mentioned before is there is some other overhead due to the setup of the codec classes.
