Details:
I have utf-8 problems in hardstatus even with the latest screen 4.6.2 from
2017.
# screen --version
Screen version 4.06.02 (GNU) 23-Oct-17
How to reproduce:
I press <ctrl-a + A> and change the window title to include a Swedish utf-8
character (like 'å' (an 'a' with a ring above it)).
If I now press <ctrl-a + "> to show the window-list, everything looks good. I
see the Swedish title correct. :-)
In the screen windows themselves (the terminal windows), my UTF-8 characters
work perfectly fine. :-)
Everything is working as intended as long as I don't have a hardstatus line.
If I let the hardstatus string print the window titles:
hardstatus on
hardstatus alwayslastline
hardstatus string '%{=b wK} %n %{Kw} %t %=@ %H %{wk} %D %M %d %c '
...then the last line will show a garbage character instead of the Swedish
'å' character.
Also there will be some internal miscalculation of the string length,
resulting in incorrect background coloring on the last lines.
In my terminal I see that the 'å' character is a two-byte-char:
# echo -n a | wc -c
1
# echo -n å | wc -c
2
(My terminal = xterm, running on Debian 9)
