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

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