Emoji

This section contains Unicode emoticons or emojis. Without proper rendering support, you may see question marks, boxes, or other symbols instead of the intended characters.

The Miscellaneous Technical block contains eighteen emoji: U+231A–U+231B, U+2328, U+23CF, U+23E9–U+23F3 and U+23F8–U+23FA.^[9]^[10]

All of these characters have standardized variants defined, to specify emoji-style (U+FE0F VS16) or text presentation (U+FE0E VS15) for each character, for a total of 36 variants.^[11]
