Details:
I get display corruption if I set hardstatus to alwayslastline and try to
display UTF-8 characters in the hardstatus. First, the UTF-8 characters are
not displayed correctly. Second, it looks like there are extra newlines in
the hardstatus such that the hardstatus takes up multiple lines at the bottom
of the terminal and lines in the regular portion of the screen are shifted out
of view.
I did not have this problem with 4.0.3 so I patched 4.2.1 with some changes I
took from 4.0.3 and the problem went away. I don't really know what I'm doing
with the screen source so the patch is just the result of poking around in the
two different versions. I'm attaching the patch in the hope that it helps one
of the screen maintainers identify the actual problem. It obviously disables
code that was deliberately added so the patch isn't really useful other than
troubleshooting.
I have also applied the hardstatus.patch that archlinux applies to their
version
of screen.
My testing was done with UXTerm on Linux
$LANG was set to "en_US.UTF-8"
screen was configured with "--enable-colors256 --enable-rxvt_osc
--disable-socket-dir"
To reproduce the problem with 4.2.1 + hardstatus.patch:
1) start uxterm and run "screen -U -c screenrc-test"
2) now that you're in screen, echo -e "\033_Núñez\033\\"
To make the problem go away, apply my utf8_lastline.patch and re-run test.
