Subject: HTML: prevent gratuitious emojification on iOS.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

iOS chooses to render a number of Unicode entities,
including '↩', as big colorful emoji.  This can be
defeated by appending Unicode
VARIATION SELECTOR-15'/'VARIATION SELECTOR-16'.
So we now append this character when escaping
strings, for both '↩' and '↔'.

If other characters prove problematic, they can
simply be added to needsVariationSelector.

Closes #5469.
