Description of Problem:
If you are running screen, some man pages are truncated and man becomes 
unusable.  It seems that some man pages are generating escape sequences that 
are not supported by screen.  This makes man completely unusable under screen.

Version-Release number of selected component (if applicable):
man 1.5j-11
screen 3.9.11-10

How Reproducible:
Reproducable

Steps to Reproduce:
1. Run 'screen'
2. Run 'man dump'

Actual Results:
Partial man page, no 'less' promp, unresponsive to keyboard input.

Expected Results:
Complete man page, 'less' prompt, responsive to keyboard input.

Additional Information:
'dump' man page one of many that seem to break under screen.  Try a few to find 
more.

Try different values for you TERM environment variable for starters:
export TERM=linux
man dump

export TERM=xterm
man dump

export TERM=vt100
man dump

All three TERM settings fail as reported.  Confirmed both on console and putty 
ssh.
Comment 3 Lon Hohberger 2002-11-11 09:35:24 EST
We built screen without UTF-8 support in Red Hat Linux 8.0.  This is because the
UTF-8 support in screen was causing more problems than it solves.  So, to fix
this, we need to tell other programs not to use UTF-8 languages (which confuse
screen):

screen

export LANG=en  (or LANG=C)

man dump

Should work.  You could put the "export LANG=en" in your .bashrc.

Changing LANG solves problems.  Thanks for quick reply.
