Re: Charsets for hex/base64

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. On Thu, May 3,

Re: Charsets for hex/base64

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

Re: Charsets for hex/base64

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

Charsets for hex/base64

Hi, Conceptually, a 'charset' (in java) is a pair of transformations from bytes to utf-16 code units and vice versa. Could it be useful to have charset implementations that convert from bytes to the hex (or base64) representations of those? The idea is as follows:
