Thanks for the explanation.

And I see now, in the 25.1 NEWS, this item:

 ** New variable 'use-default-font-for-symbols', for backward compatibility.
 This variable allows you to get back pre-Emacs 25 behavior where the
 font for displaying symbol and punctuation characters was always
 selected according to your fontset setup.  By default, Emacs 25 tries
 to use the default face's font for such characters, if it supports
 them, disregarding the fontsets.  Set this variable to nil to disable
 this and get back the old behavior.

I guess that explains it (though I would have expected also a NEWS
item about the behavior change, separate from that item mentioning
a new variable).
