surrogate
Also called 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 represent a character as a pair only and not directly. The ABAP programming language supports UCS-2, which means mainly UTF-16 without surrogates, and interprets a surrogate character as two characters.
