Provide de-normalisation

Well, you have convertor ANY -> technically_correct/ It will be nice if you write ANY -> human_readable

i.e. ANY -> normalized -> human_readable.

Human-readable mean (idna -> unicode) + unscape of percent-encoding. unsecape should be done in a way where

X = ANY -> normalized Y = normalized -> human_readable Z = human_readable -> normalized assertEqual (X, Z)
