I am running 30+ servers at SLES 11 SP3 on System z. On most of the servers the lines that make up the boxes are now letters.

  x                                                                      YaST2 Control Center                                                                       x
One of my servers displays the lines correctly.

  │                                                                      YaST2 Control Center                                                                       │

If I ssh from this server to the server that displays the lines incorrectly and launch yast, yast displays the lines properly.

I found a thread that addressed a similar issue from Feb 2013 but it didn't have a resolution, it said to open an SR. I have issued "locale" on each of these servers and the display is the same.

How can I correct this? The problem makes the display hard to read with all of the extra alphabetic characters (as opposed to the line drawings).
