Interestingly, Guidos latex mode has a rule

  % all the rest
  dfa_define_highlight_rule (".", "normal", name);

that does not help overcome this problem. (But why?)

I assume, that with DFA syntax highlight in place, the "standard" routine
for displaying multi-byte chars is bypassed.  Now, if there is no special
treatment by DFA highlighting routines (as no colour is defined) the
fallback display method for unprintable chars is used.

John, is this a bug or a feature?

It does. I fixed all my DFA highlighting modes and will upload to
Jedmodes soon. 

This removed the last obstacle for switching my system to UTF-8.
