707 * the hex-dump window (except by punting and displaying only
710 * GTK+ 2.0 may simplify part of the problem, as it will, as I
711 * understand it, use UTF-8-encoded Unicode as its internal
712 * character set; however, we'd still have to know whatever
713 * character set and encoding is used in the packet (which
714 * may differ for different protocols, e.g. SMB might use
715 * PC code pages for some strings and Unicode for others, whilst
716 * NFS might use some UNIX character set encoding, e.g. ISO 8859/x,
717 * or one of the EUC character sets for Asian languages, or one
718 * of the other multi-byte character sets, or UTF-8, or...).
720 * I.e., as far as I can tell, "internationalizing" the packet-list,
721 * protocol-tree, and hex-dump windows involves a lot more than, say,
722 * just using font sets rather than fonts.
