683 * Making this a font set rather than a font has two problems:
685 * 1) as far as I know, you can't select font sets with the

688 * 2) if you use a font set, the text to be drawn must be a
689 * multi-byte string in the appropriate locale, but

692 * of the display must be a *single* byte, and in the
693 * packet-list and protocol-tree windows, text extracted
694 * from the packet is not necessarily in the right format.
696 * "Doing this right" may, for the packet-list and protocol-tree
697 * windows, require that dissectors know what the locale is
698 * *AND* know what locale and text representation is used in
699 * the packets they're dissecting, and may be impossible in
700 * the hex-dump window (except by punting and displaying only
703 * GTK+ 2.0 may simplify part of the problem, as it will, as I
704 * understand it, use UTF-8-encoded Unicode as its internal
705 * character set; however, we'd still have to know whatever
706 * character set and encoding is used in the packet (which
707 * may differ for different protocols, e.g. SMB might use
708 * PC code pages for some strings and Unicode for others, whilst
709 * NFS might use some UNIX character set encoding, e.g. ISO 8859/x,
710 * or one of the EUC character sets for Asian languages, or one
711 * of the other multi-byte character sets, or UTF-8, or...).
713 * I.e., as far as I can tell, "internationalizing" the packet-list,
714 * protocol-tree, and hex-dump windows involves a lot more than, say,
715 * just using font sets rather than fonts.
