Further information, as mentioned in a comment on StackOverflow
(https://emacs.stackexchange.com/questions/38449/ubuntu-mono-font-hanging-emacs?noredirect=1#comment60603_38449):
Changing `query-replace-from-to-separator` to something trivial such
as " -> " also fixes the problem. This suggests that there is (1)
likely something "different" with Ubuntu Mono's interpretation of the
right-arrow character, and (2) emacs is not dealing well with that
different-ness.
Is `query-replace' necessary to trigger the bug, or does evaling
(message "%s" query-replace-from-to-separator)
a couple of times also hang Emacs?
