I have been trying to find why the "alternate characters" from xterm don't work anymore in screen. You can see this in mutt for instance, if you have set ascii_chars=no and order by thread. You get letters when using screen, but when using a bare xterm you get the proper line drawing characters.

I originally reported this at
which was partially resolved, but not completely. Please look at the full history (and patch) there.

ACS work fine on 32-bit systems but not on 64-bit.

"I found out that my fix only fully works if TERM=vt100 before you start screen. If TERM=xterm, it only works half: no OOPSes, but the alternate characters are not shown in the alternate character set (so instead of line drawing you get some letters).
This does work on i386 (although that binary was compiled a lot longer ago). There must be some other 64-bit bug lurking somewhere. It's not that the termcap entry for xterm is too long, since it is just within the 1024 bytes mark."
