AFAIK, std::codecvt is defined in <locale>, not <codecvt>. Also note
that by default the ODB compiler compiles in the C++98 mode so the
new UTF-8/UTF-16 stuff won't be available. To switch to the C++11 mode
you will need to pass '--std c++11' option.

Right, that's exactly what we are planning to do. However, there are
some architectural issues that we first need to resolve to be able
to support such "dual images" (i.e., TEXT can be mapped to a UTF-8
or UTF-16 image). Also, once we have this worked out, it will also
be fairly straightforward to add support for streaming BLOB interface
