If your program shall run only in the same locale as the one in which
you compile it -- i.e. basically if you write it only for yourself --
then you can write

  const char * string = "UTF-8 encoded string, use an UTF-8 enabled editor";

But if your program shall run in different locales, possibly with
different character sets, you should use GNU gettext and write

  const char * string = gettext ("an ASCII string serving as key");

Here you need to use 'wchar_t' instead of 'char'. And where you use
the printf directive %c to print a 'char', you use the directive %lc
to print a 'wchar_t'.
