Resending to LFS mailing list since kbd is included in that book as well
as old posts you've mentioned:

Unfortunately it didn't help (even recompiled kbd with patch applied).
I have system with LANG=en_US.UTF-8, which should be the default.
However I currently have Norwegian keyboard and I would really like to get
all *?- etc.symbols in the right place.
- I don't have any issues if I use ssh connection, only on local terminals.
- Square blocks are appearing only if symbol deleted within a text (i.e. not
  the last one) and usually after deliting at least 2 symbols.
- Square blocks are appearing till the end of screen even if there was no text
  there with black space between white.
- while deleting yet one more symbol whole line became white (one more
  black position became white).

I've noticed, that I don't need to edit text to get problem visisble, just
scroll text in mcedit. For example scrolling dircolors file get this problem
100%. Position on the terminal screen remains white even if I quit mcedit.

At least LANG=en_US.UTF-8 and non-us keyboard are working file with Ubuntu...
I wonder what's wrong with my LFS setup...
