I feel like what you're looking for is really a general-purpose data
transformation API. I think bending charsets into this shape would be
a bad move, but I like the idea of a more generalized solution.
Google Guava has such an abstraction, and I know of a couple of others
a well.

Well technically there is some sort of precedent to this, since
CharsetEncoder/Decoder operate on CharBuffers which are just utf-16
encoded strings. So charsets already may produce a single output code
*unit* for multiple input code units (UTF-32, which may output 1 code
unit for 2 UTF-16 input
FYI here’s the javadoc for a draft of the Hex API that Alan mentioned below:

Thanks.

Normally a charset is to encode a string to byte[], but here you can actuall
I did not know about the old HexDumpEncoder. It extends an internal
class `CharacterEncoder` which seems to be pretty similar purpose-wise
to what I am suggesting with CharsetEncoder. There is also the good old
`DatatypeConverter.printHexBinary`, though it can't stream.
But this is not really
