High Surrogates Unicode Characters page 1

The High Surrogates block is part of the UTF-16 encoding system used in Unicode to represent characters outside the Basic Multilingual Plane (BMP), which includes characters with code points above U+FFFF. High surrogates are used in pairs with low surrogates to form a surrogate pair, which together represent a single character in the supplementary planes. This block is essential for encoding and decoding text in digital formats that use UTF-16, ensuring that all characters in Unicode, including those in supplementary planes, can be accurately represented..
