Box characters not displayed correctly under screen
Last modified: 2007-04-18 12:35:32 EDT
Description of Problem:
Box drawing character are not displayed properly, and backspace doesn't
work with ash as my shell.
Happens every time
Steps to Reproduce:
1. run the yesno sample dialog script under screen in a console
2. observe incorrect lower border and left border box characters
Incorrect characters displayed, back space fails to backspace
good box characters, back space erases character to left
These experiments were run in a console window, not an xterm.
what you running it on? console or xterm or rvt or gnometerm?
I can see silliness on a console but that is really down to a duff termcap
see if you export TERM=vt100 it's fine (admittidly in black and white,..)
Now I'm unsure which file it's reading for the info /etc/termcap or
One is from the termcap package and the otehr from ncurses. I'm going to make a
stab at termcap being the guilty party
Over to you Bero 8)
We assume, you mean with 'console' a replacement for a real
system-console (Alt F1 or Ctrl Alt F1) == non graphic mode
We have tested your scenario on FEDORA CORE 4.
We have tried to launch (on 'console') (default settings):
yesno (yes-no-example-dialog) works, but some semigraphic
characters are not correctly displayed, keys are
If we launch (on command prompt):
Now, 'yesno' works fine, alle semigraphic characters are
correctly interpreted/displayed, keys are correctly interpreted.
NOTE: The 'box' (== semigraphic characters == ACS_HLINE, ACS_VLINE,...)
are displayed only, if the current font 'supports' this
