Copying ASCII isn't desirable.  It should copy the Unicode string "a → b".
After all, that's what gets copied if you had done "<span>a → b</span>" in
the first place.

(Chrome's issue isn't related to Unicode.  It just doesn't know how to
select text that's inside CSS content, so it isn't included in the copy.)
