The creepy crawly spidery font that occurs in Emacs-28 between quote
marks, by default, was something I lived with to the moment it was
raised in a thread on emacs-devel.   Then on, I followed the discussion
on fonts to improve that setting.   And, pieced together the info that
is at the head of this thread.   Another discomfort I live with is a
long delay when I first open a file with a mix of CJ asia east fonts.

The delay is about as long as the time it takes to transfer a 4Gb data
file.   Attached is a capture of the packet traffic activity.
