This is likely an issue with handling wide characters in streams.
Many standard library implementations have quirks in this area
and our utf-8 facet is likely not perfect either.

On the upside, this is fairly easy to track down.

a) the library builds - that's OK - build in debug
b) run the failing test with the debugger.  I presume
that's GDB in this case.  Set it so that it traps when throwing
on a C++ exception.  They you can see a back trace
as well as the code that failed.  At that point it may or
may not be obvious what to do.  But at least getting
to that point is pretty easy.
