You are lucky that that worked. It's unlikely to work with multi-byte
UTF-8 characters such as Asian characters.

The exception is actually coming from your use of << with the standard C
++ stream. The standard C++ streams can't do UTF-8 so there is an
automatic conversion. See "streams input/output" here:
http://www.gtkmm.org/docs/glibmm-2.4/docs/reference/html/classGlib_1_1ustring.html#_details

The answer, I think, is Just don't use std::cout and friends to show
UTF-8.
