1106 * selection in the global preferences file to make that font the
1107 * default for all users who don't explicitly specify a different
1110 * Making this a font set rather than a font has two problems:
1112 * 1) as far as I know, you can't select font sets with the
1113 * font selection dialog;
1115 * 2) if you use a font set, the text to be drawn must be a
1116 * multi-byte string in the appropriate locale, but
1117 * Wireshark does *NOT* guarantee that's the case - in
1118 * the hex-dump window, each character in the text portion
1119 * of the display must be a *single* byte, and in the
1120 * packet-list and protocol-tree windows, text extracted
1121 * from the packet is not necessarily in the right format.
1123 * "Doing this right" may, for the packet-list and protocol-tree
1124 * windows, require that dissectors know what the locale is
1125 * *AND* know what locale and text representation is used in
1126 * the packets they're dissecting, and may be impossible in
1127 * the hex-dump window (except by punting and displaying only
1128 * ASCII characters).
1130 * GTK+ 2.0 may simplify part of the problem, as it will, as I
1131 * understand it, use UTF-8-encoded Unicode as its internal
1132 * character set; however, we'd still have to know whatever
1133 * character set and encoding is used in the packet (which
1134 * may differ for different protocols, e.g. SMB might use
1135 * PC code pages for some strings and Unicode for others, whilst
1136 * NFS might use some UNIX character set encoding, e.g. ISO 8859/x,
1137 * or one of the EUC character sets for Asian languages, or one
1138 * of the other multi-byte character sets, or UTF-8, or...).
1140 * I.e., as far as I can tell, "internationalizing" the packet-list,
1141 * protocol-tree, and hex-dump windows involves a lot more than, say,
1142 * just using font sets rather than fonts.
