0x01D40

0x01D40 is a hexadecimal numeral commonly used in programming and digital encoding. In the Unicode standard, the code point corresponding to this value is U+01D40, which lies in the Phonetic Extensions block (Unicode range U+01D00 to U+01D7F). The decimal equivalent of 0x01D40 is 7488.

The Phonetic Extensions block contains characters used for phonetic transcription, and U+01D40 represents one of these symbols. The exact character and its formal Unicode name are defined in the Unicode database, and its appearance depends on font support for IPA (International Phonetic Alphabet) symbols. Rendering may vary across fonts and platforms, with some environments displaying a placeholder if the symbol is not supported.

In practical terms, 0x01D40 may appear in linguistic software, academic literature, and language technology where precise phonetic notation is required. It is not part of ASCII and requires Unicode-compliant systems to be represented and processed correctly. When identifying or exchanging text that includes this code point, it is common to refer to it by its Unicode designation (U+01D40) rather than the hexadecimal literal, to avoid ambiguity across programming languages and data formats.

Overall, 0x01D40 functions as a hexadecimal shorthand for a Unicode phonetic symbol in the IPA-related Phonetic Extensions block, illustrating how hex literals map to standardized characters in modern text encoding.
