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