* XXX - for now, we make the initial font name a pattern that matches

* as ISO 10646 fonts.
*
* 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.
