Have you considered using boost.iostreams lib to directly write to your
alternate string type?

The tutorial 2.1.3 in the docs:

Describes a generic container_sink, but also describes using
iostreams::back_inserter. This could be wrapped in a generic function
that returns your desired string type. Assuming of course that the type
is back insertable.
