On Linux, any GUI build of Vim can also double as a Console version, so
it needs some ncurses package in addition to its GTK, Motif or whatever
GUI package.

My GTK2/Gnome2 gvim has -lncurses as one of the space-separated
arguments on its "Linker" line. It can display hanzi with no problem in
GUI mode, or in a konsole terminal. In xterm many hanzi are replaced by
empty rectangles, but not all, so I suppose the font used by my xterm
terminal hasn't got all the needed glyphs. mlterm is better than xterm
but not as good as konsole. The Linux console is worse than anything:
there, even U+4E00 (the number one, a single horizontal strike) is shown
as a reverse-video question mark.

Best regards,
Tony.
