This doesn't look right to me. Hex-encoded "data" is really text (it's
a textual representation of binary, and isn't often used as an opaque
binary transport encoding).
Of course, this is not necessarily so for all codecs. For
base64-encoded data, for example, it is debatable whether you want it
as ASCII bytes or unicode text.
