Does it work if you call setlocale(LC_ALL,"") (or with glibmm,
std::locale::global(std::locale("") ) before you attempt any
conversions?

If not, it looks as if your editor is writing the string literal into
your code in a codeset which represents the characters "hello"
differently than UTF-8/ASCII does (g_locale_from_utf8() has to be
passed valid UTF-8).
