注释
	^ Unicode range D800–DFFF is used for surrogate pairs in UTF-16 (used by Windows) and CESU-8 transformation formats, allowing these encodings to represent the supplementary plane code points, whose values are too large to fit in 16 bits. A pair of 16-bit code points — the first from the high surrogate area (D800–DBFF), and the second from the low surrogate area (DC00–DFFF) — are combined to form a 32-bit code point from the supplementary planes. Unicode and ISO/IEC 10646 do not assign actual characters to any of the code points in the D800–DFFF range — these code points only have meaning when used in surrogate pairs. Hence an individual code point from a surrogate pair does not represent a character, is invalid unless used in a surrogate pair, and is unconditionally invalid in UTF-32 and UTF-8 (if strict conformance to the standard is applied).
