/*
 * XXX - "isprint()" can return "true" for non-ASCII characters, but
 * those don't work with GTK+ 1.3 or later, as they take UTF-8 strings
 * as input.  Until we fix up Ethereal to properly handle non-ASCII
 * characters in all output (both GUI displays and text printouts)
 * in those versions of GTK+, we work around the problem by escaping
 * all characters that aren't printable ASCII.
 *
 * We don't know what version of GTK+ we're using, as dissectors don't
 * use any GTK+ stuff; we use GLib as a proxy for that, with GLib 2.x
 * implying GTK+ 1.3 or later (we don't support GLib 1.3[.x]).
