0x1D31

0x1D31 is the hexadecimal encoding of the Unicode code point U+1D31. This code point resides in the Phonetic Extensions block (U+1D00–U+1D7F) of the Unicode standard, a range designated for additional symbols used in phonetic transcription, particularly in linguistic work involving the International Phonetic Alphabet (IPA). The exact glyph for U+1D31 can vary by font, as with many IPA-related characters, and is primarily encountered by linguists, typographers, and software that supports IPA data.

In terms of encoding, U+1D31 lies within the Basic Multilingual Plane, so UTF-16 represents it with a single 16-bit unit (0x1D31). In UTF-8, the code point is encoded as three bytes: E1 B4 B1. This makes it accessible to modern text systems that rely on UTF-8, which is widespread across the web and software platforms.

The character’s primary relevance is linguistic notation rather than general-purpose text processing. It illustrates how Unicode accommodates specialized symbols used in phonetic transcription, alongside other IPA-related symbols in the same and neighboring blocks. Users seeking to render it should ensure their font supports the Phonetic Extensions and IPA-related characters to display the intended glyph correctly.
