917 * only ISO 8859/1 fonts, so that we don't match 2-byte fonts such
918 * as ISO 10646 fonts.
920 * Users in locales using other one-byte fonts will have to choose
921 * a different font from the preferences dialog - or put the font
922 * selection in the global preferences file to make that font the
923 * default for all users who don't explicitly specify a different
926 * Making this a font set rather than a font has two problems:
928 * 1) as far as I know, you can't select font sets with the
929 * font selection dialog;
931 * 2) if you use a font set, the text to be drawn must be a
932 * multi-byte string in the appropriate locale, but
933 * Ethereal does *NOT* guarantee that's the case - in
934 * the hex-dump window, each character in the text portion
935 * of the display must be a *single* byte, and in the
936 * packet-list and protocol-tree windows, text extracted
937 * from the packet is not necessarily in the right format.
939 * "Doing this right" may, for the packet-list and protocol-tree
940 * windows, require that dissectors know what the locale is
941 * *AND* know what locale and text representation is used in
942 * the packets they're dissecting, and may be impossible in
943 * the hex-dump window (except by punting and displaying only
946 * GTK+ 2.0 may simplify part of the problem, as it will, as I
947 * understand it, use UTF-8-encoded Unicode as its internal
948 * character set; however, we'd still have to know whatever
949 * character set and encoding is used in the packet (which
950 * may differ for different protocols, e.g. SMB might use
951 * PC code pages for some strings and Unicode for others, whilst
952 * NFS might use some UNIX character set encoding, e.g. ISO 8859/x,
953 * or one of the EUC character sets for Asian languages, or one
954 * of the other multi-byte character sets, or UTF-8, or...).
956 * I.e., as far as I can tell, "internationalizing" the packet-list,
957 * protocol-tree, and hex-dump windows involves a lot more than, say,
958 * just using font sets rather than fonts.
