Indeed. I'll try to pinpoint source of problem another day.

yes no problem with my initializations, but my command line emacs 22
does not share the exact same initializations as my GUI Emacs, although
a lot is common

(I have a common .emacs which checks the version and then uses
suitable files from .emacs.d, for example custom.el for GUI Emacs versus
custom22.el for emacs 22; I stopped modifying these custom22.el and init22.el
years ago, but the ones for GUI Emacs continue evolving from time to
time. These days I am lazy and I have spent months now cursing my
fill-column setting which following last update to my Emacs binary seems to
be
at 70 per default in many modes, whereas I largely prefer 78 or 79 and had
it this way earlier,
but not time to dig into my Emacs initializations and why the mode-hooks do not
work as they used too so far)

I will try to pinpoint cause of combining character issue another day...
... as I never use combining Unicode characters to start with...
