D83D is a hexadecimal value that functions as a high surrogate in UTF-16 encoding. It is not a standalone Unicode code point or character. In the Unicode system, code points above U+FFFF are encoded using pairs of 16-bit code units known as surrogate pairs. The high surrogate occupies the range D800–DBFF, and D83D is one particular value within that range used to begin such a pair.
When D83D is paired with a corresponding low surrogate in the range DC00–DFFF, together they encode a
In practice, D83D often appears in contexts dealing with emoji and Unicode text interchanges, especially in
