With my wl-pprint-text package, Jason Dagit suggested to me on #haskell that it would make sense to make such a pretty-printer be class-based so that the same API could be used for String, ByteString, Text, etc.

I'm a bit skeptical of using type classes to abstract over Unicode string types and byte sequence types. The only API shared by the two kind of types is that of a sequence. Things like dot , spaces, etc. don't make much sense on binary data. You must assume that the ByteString contains text in some encoding to make sense of such concepts. Johan
