777 * PC code pages for some strings and Unicode for others, whilst
778 * NFS might use some UNIX character set encoding, e.g. ISO 8859/x,
779 * or one of the EUC character sets for Asian languages, or one
780 * of the other multi-byte character sets, or UTF-8, or...).
782 * I.e., as far as I can tell, "internationalizing" the packet-list,

784 * just using font sets rather than fonts.
