A surrogate is a Char object with a UTF-16 code unit in the range from U+D800 to U+DFFF. Each character with a code unit in this range belongs to the UnicodeCategory.Surrogate category. The individual surrogate code unit has no interpretation of its own, but has meaning only when used as part of a surrogate pair. For more information about surrogate pairs, see the Unicode Standard at the Unicode home page.
