634 * Users in locales using other one-byte fonts will have to choose
635 * a different font from the preferences dialog - or put the font
636 * selection in the global preferences file to make that font the
637 * default for all users who don't explicitly specify a different
640 * Making this a font set rather than a font has two problems:
642 * 1) as far as I know, you can't select font sets with the
643 * font selection dialog;
645 * 2) if you use a font set, the text to be drawn must be a
646 * multi-byte string in the appropriate locale, but
647 * Ethereal does *NOT* guarantee that's the case - in
648 * the hex-dump window, each character in the text portion
649 * of the display must be a *single* byte, and in the
650 * packet-list and protocol-tree windows, text extracted
651 * from the packet is not necessarily in the right format.
653 * "Doing this right" may, for the packet-list and protocol-tree
654 * windows, require that dissectors know what the locale is
655 * *AND* know what locale and text representation is used in
656 * the packets they're dissecting, and may be impossible in
657 * the hex-dump window (except by punting and displaying only
660 * GTK+ 2.0 may simplify part of the problem, as it will, as I
661 * understand it, use UTF-8-encoded Unicode as its internal
662 * character set; however, we'd still have to know whatever
663 * character set and encoding is used in the packet (which
664 * may differ for different protocols, e.g. SMB might use
665 * PC code pages for some strings and Unicode for others, whilst
666 * NFS might use some UNIX character set encoding, e.g. ISO 8859/x,
667 * or one of the EUC character sets for Asian languages, or one
668 * of the other multi-byte character sets, or UTF-8, or...).
670 * I.e., as far as I can tell, "internationalizing" the packet-list,
671 * protocol-tree, and hex-dump windows involves a lot more than, say,
672 * just using font sets rather than fonts.
