I'll send this patch to T. Dickey. 

I've sent this patch now to Thomas E. Dickey for inclusion for a future 
release. No reply yet.

I saw it, noticed that it needs some more work (it's on my to-do list).

One troubling aspect of this is that it will tend to decrease
portability of applications, is unrelated to any standard.
Bug #1841 cites an example of this.

*** Bug 1841 has been marked as a duplicate of this bug. ***

I tried Stefan's patch. It's okay for me if I have "*locale: false".
However if I have "*locale: true" and hence use luit to convert to latinX then
the IUTF8 flag of the terminal is always set, even if I use Latin2 (LANG=hu_HU)
mode where it shouldn't be set.

So at least luit has to be patched also...

CC:'ing i18n/X11 folks from Sun to take a look at the patch, too...

well, then I have this chunk now
(am trying to tie off loose ends to close out patch #197):

#if OPT_WIDE_CHARS && defined(linux) && defined(IUTF8)
#if OPT_LUIT_PROG
                if (command_to_exec_with_luit == 0)
#endif
                if (screen->utf8_mode)
                    tio.c_iflag |= IUTF8;
#endif

I committed the change noted in xterm patch #197.

Thanks!

Oh, wait please!
Please make sure that not only xterm is correct on its own, but even
standalone luit properly sets or clears this flag depending on whether
it is run with an utf8 locale or not.
This is because luit is not only used by xterm, it's really usable on its own.
