 I'm still having difficulty envisioning what is happening on
Alexey's system, but I guess it might be down to an invalid unicode
character (assuming he is using UTF-8), and that his chosen font
doesn't display those sanely [ U+FFFD should be generated for this in
a unicode locale, preferably as a reverse-video question mark "�" ].

 Other things to consider:

 What are the locales (LC_ALL or similar) in BOTH systems ?

 Using 'showkey' [ in a tty ], find the values for the Backspace and
Del keys - on a regular 102-key keyboard mine are 14 and 111 - then
use 'dumpkeys | less' to find what is output for those keys - mine
are 'Delete' and 'Remove' : for no-latin1 the latter is corrected in
the patch.  I _think_ ubuntu has versions of both those commands
(from console-tools), so you could compare them.

 The backspace and delete keys are sufficiently common that the
LEGACY_CHARSET variable (LFS section 7.10) probably doesn't come
into play - but it might be needed to fix up other symbols if you
are using UTF-8 and the keymap is iso-8859-something.

das eine Mal als Tragödie, dieses Mal als Farce
