What you are missing is that you never once tried the combination setting
I described as causing problem. Please try to set a non-utf8 _country_
locale for the LANG variable together with a utf8 locale for the LC_ALL
variable. E.g. at your zsh prompt:

   export LANG=de_DE
   export LC_ALL=de_DE.utf8
   
type in e.g. an umlaut character, type backspace to delete it and notice
that it is deleted piecemeal by octet. It should happen to you too!
Despite the sillyness of this locale combination, zsh should not
deactivate multibyte support. I can do exactly the same in bash and there
is no problem. I do not see how this could be anything in my setup. I
tried to load zsh with the -f parameter and it makes no change. There
were no locale related settings in my ~/.environment. This combination

   export LANG=
   export LC_ALL=da_DK.utf8

is okay. So it is the specific combination of a non-utf8 country locale
for LANG and a utf8 country locale for LC_ALL that is at fault.
