Unicode: Surrogate Pair

What is Surrogate Pair

Surrogate Pair is a sequence Codepoints used in UTF-16 Encoding , that forms one character.

• Codepoints in the range U+D800 to U+DBFF (1024 of them) are known as high-surrogate codepoints
• Codepoints in the range U+DC00 to U+DFFF (1024 of them) are known as low-surrogate codepoints.

A high-surrogate codepoint followed by a low-surrogate codepoint form a surrogate pair in UTF-16 to represent code points greater than U+FFFF.
