HTML: prevent gratuitious emojification on iOS. 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.
