The general idea is to set the locale (i.e. call `setlocale()`) and
then perform a multibyte to widechar translation. Since `wchar_t` does
not specify an encoding (i.e. the encoding varies from one platform to
another) you will need to make sure that your translation correctly
converts the input string to the desired *native* encoding. Little
endian UTF-16 is the encoding of choice on Windows platforms.
C++11 has `codecvt_facet` which may interest you.
