Surrogate code points are intended to allow mapping of additional character planes into the 16-bit Unicode system, thus allowing more than 65,536 characters to be represented. The individual surrogate code points do not represent characters; they are intended to be used in pairs, a high code point followed by a low code point, to stand in for a character in one of the supplementary planes. Their use is restricted to UTF-16. They can be used for characters in Linear B Syllabary and higher-numbered ranges.
