The `scodec.codecs.cstring` codec supports `NUL` terminated US-ASCII. I just added `codec.codecs.nulTerminatedString` which can be used for other charsets.

The [scodec-cats](https://github.com/scodec/scodec-cats) project defines cats type class instances for scodec types. There might be some missing but the major ones should all be covered. Re: shapeless-derived, I tried using it...

@lenguyenthanh Sure, sounds good!

If someone wants to get this in to a mergeable state again, for sure.

Thanks @cranst0n!

Definitely former. :) This bug makes us skip on a small optimization in FS2's `Files[F].walk` routine (on native only).

This is brilliant!

Note this isn't unique to string multiplication - it's a bug in syntax highlighting of very long strings.
