D835

D835 is a hexadecimal value that designates a UTF-16 code unit. It resides in the high-surrogate range of 0xD800 to 0xDBFF, which are used as the first part of surrogate pairs in Unicode encoding.

In UTF-16, characters outside the Basic Multilingual Plane (those with code points above U+FFFF) are encoded as surrogate pairs. A high surrogate (such as 0xD835) must be followed by a low surrogate, in the range 0xDC00 to 0xDFFF, to form a single Unicode code point.

The specific code point encoded by a pair that starts with D835 depends on the accompanying low surrogate. Using the standard formula, codepoint = 0x10000 + ((high - 0xD800) << 10) + (low - 0xDC00), a high surrogate of D835 paired with a low surrogate in DC00–DFFF yields code points in the range U+1D000 to U+1D7FF. For example, D835 DC00 encodes U+1D000.

In practical terms, D835 is not a standalone character. It appears in text as part of a surrogate pair when UTF-16 encoding is used. Many programming languages and data formats that rely on UTF-16 must handle surrogate pairs correctly to process, display, or interchange text without errors.
