Emoji

The Miscellaneous Technical block contains eighteen emoji: U+231A–U+231B, U+2328, U+23CF, U+23E9–U+23F3 and U+23F8–U+23FA.^[6]^[7]

The block has 30 standardized variants defined to specify emoji-style (U+FE0F VS16) or text presentation (U+FE0E VS15) for the following fifteen base characters: U+231A–U+231B, U+2328, U+23CF, U+23E9–U+23EA, U+23ED–U+23EF, U+23F1–U+23F3 and U+23F8–U+23FA.^[8]
