Also referred to as surrogate pair. Combination of special low and high surrogate characters for addressing characters in the surrogate area when using UTF-16. High surrogate characters range from U+D800 to U+DBFF. Low surrogate characters range from U+DC00 to U+DFFF. They are called surrogates since they do not directly represent a character, they only do so as a pair. ABAP interprets a surrogate character as two characters.
