Neither has LC_ALL set

Ubuntu and LFS-7.4 had this set:

On all systems showkey output is:
BS - keycode  14 and DEL -keycode 111
dumpkeys has 'Delete' and 'Remove'

After deeper investigation I got really confused....
BS/DEL problem exists in en_US layout and appearing while I'm deleting
SPACE symbol with BS within a string like "kkkkk kkkk".

I've changed LANG to LANG=en_US.ISO-8859-1 and UNICODE=0 and
problem is still there, however on old LFS-6.3 everything works fine with
LANG=en_US.ISO-8859-1 and even with "loadkeys no-latin1".

Problem looks like described in BLFS Chapter 2. Important Information,
Locale Related Issues: "The Program Breaks Multibyte Characters or
Doesn't Count Character Cells Correctly"

Since issue is present even with US keyboard layout, I wonder if ALFS
build did something funny during build (or didn't do something right).

I've tried to rebuild kbd with a patch, but didn't help.

If I log via ssh everyhting looks ok. Is it because I use other pc
facilities in this case?
