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