'Recode' is a great name for the conceptual process, but the methods
are directional.  Also, in internationalization work, "recode"
strongly connotes "encodingA -> original -> encodingB", as in iconv.

I do prefer constructors, as it's generally not a good idea to do
encoding/decoding in-place for human-readable text, since the codecs
are often lossy.

Unlikely.  Errors like "A string".encode("base64").encode("base64")
are all too easy to commit in practice.
