Hi,

I’ve run into an annoyance when using ssh to access a ubuntu system.  When
using vi or vim, the screen doesn’t refresh properly when paging
forward/backward using ctrl-f/ctrl-b.  What happens is I get a union of
non-space characters between the old page and the new page.  So if a
character is a space on the first page and in that location a non-space
character is on the second page, then the non-space character is written.  If
the second page has a space, then it doesn’t replace whatever was on the
screen from the first page.  On the other hand, if I scroll one line at a
time, it works correctly (just annoying if I’m trying to go through a large
file).  Any ideas how to fix this?  I’m using XQuartz 2.7.11.  Odd thing is,
it only does it on my macs with 10.13, my laptop that still has 10.12 does
not have this problem.

offhand, it looks like an encoding problem: Ubuntu's setup for UTF-8
encoding and the default configuration for xterm is ISO-8859-1.
You should be able to use the "uxterm" script (which sets the encoding).
