Comment (by pento):

 In [attachment:"46404.2.diff"]:

 - Switch to using UTF-16 hex numbers for the test, rather than having to
 manually convert them to decimal.
 - Use a new emoji from Emoji 12: [https://emojipedia.org/men-holding-
 hands-medium-dark-skin-tone-medium-light-skin-tone/ men holding hands with
 different skin tones].
 - Document criteria for test emoji for future updates.

 I've tested that this functions correctly on:
 - Android 2.2, 4, 6, 7, 8 + Chrome
 - Windows XP + IE6
 - Windows 8.1 + Chrome, Firefox
 - iOS 6, 12 + Safari

 It does not function on:
 - iOS 3 (emoji aren't replaced)
 - iOS 4/5 (emoji are replaced, but images are squashed)
