Why would you care ? The API lets you plug in your own unicode string type,
so you can access the data and map it to whatever encoding you want.

Of course, the choice of the encoding used by the backend will have an
impact on performance and memory usage, and it would be nice if that could
be tuned by the user. Yet, that is an implementation detail. If we require
backends to *use* different encodings internally I'm afraid that will reduce
the choice a lot (I'm actually not aware of any implementation that gives
such a choice).

Have a look into the code !
I admit right now it's totally trivial, as it only provides functions
to convert in and out between the externally visible unicode type and
the type libxml2 uses ('xmlChar *'). There isn't even an explicit second
template parameter for it, as I deduce it from the first. If that proves
to be insufficient, I'll add it as an explicit second parameter to all
types.
