Martin, Sherman thanks for clarification!
Closing the bug as not a bug.
> The "character" in the nio Charset and CharDe/Encoder is specified as

> that will be produced for each character of input" to be the Java
> "char" as well. In case of
> UTF8, each 4-byte form supplementary character is always coded into 2
> surrogate chars,
> it's "2 byte per char".
> Do we have a real escalation that complains about this?
