If you run it natively under xterm, it looks fine. If I run it under "LANG=C luit", the first half of each ACS block looks fine but the second half is in ASCII, I think because the shift state isn't being restored.

something like that (luit's design limits the types of shifts it supports,
so vttest will probably never look right in that screen).

(And if I just run "luit" by itself (with, e.g., LANG=en_US.UTF-8), none of the ACS characters work right because luit is just translating from UTF-8 to UTF-8.)

But I've used it with ncurses, by modifying luit to set NCURSES_NO_UTF8_ACS. Ordinary termcap applications won't know about that.
