I missed the ^N out for simplicity, and in graphics mode k is a
top-right corner character. What I'm doing is something like this:

/--stuff--more stuff--some more stuff--------------------

and I am then truncating this to the screen width with \ (using / and \
for top-left and top-right corner characters respectively). The border
is in graphics mode and bold cyan while the various stuffs are in
various colours and normal text mode, so if it gets truncated in the
middle of them I am getting a text letter k in whatever colour happens
to be there. Therefore I want to set the colour and have a ^N in the
truncating string.

Any ideas?
