/* It appears that isprint() is not working well
 * with gtk+'s text widget. By narrowing down what
 * we print, the ascii portion of the hex display works.
 * MSVCRT's isprint() returns true on values like 0xd2,
 * which cause the GtkTextWidget to go wacko.
 *
 * (I.e., whilst non-ASCII characters are considered printable
 * in the locale in which Ethereal is running - which they might
 * well be, if, for example, the locale supports ISO Latin 1 -
 * GTK+'s text widget on Windows doesn't seem to handle them
 * correctly.)
 *
 * This is a quick fix for the symptom, not the
 * underlying problem.
