Step 1: Determine the UTF-8 encoding bit layout
The character ᵇ has the Unicode code point U+1D47. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800to0xffff.
Therefore we know that the UTF-8 encoding will be done over 16 bits within the final 24 bits and that it will have the format:1110xxxx 10xxxxxx 10xxxxxx
Where thexare the payload bits.UTF-8 Encoding bit layout by codepoint range Codepoint Range Bytes Bit pattern Payload length U+0000 - U+007F 1 0xxxxxxx 7 bits U+0080 - U+07FF 2 110xxxxx 10xxxxxx 11 bits U+0800 - U+FFFF 3 1110xxxx 10xxxxxx 10xxxxxx 16 bits U+10000 - U+10FFFF 4 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx 21 bits Step 2: Obtain the payload bits:
Convert the hexadecimal code point U+1D47 to binary:
00011101 01000111. Those are the payload bits.Step 3: Fill in the bits to match the bit pattern:
Obtain the final bytes by arranging the paylod bits to match the bit layout:
11100001 10110101 10000111

Description
The Unicode character U+1D47, known as the Modifier Letter Small B (ℬ), plays a crucial role in digital text, particularly in phonetic transcription and linguistic annotation. This character serves as a modifier for the following letters: A, E, I, O, U, Y, and W, when they require a small b to represent the difference between voiced and voiceless sounds or to differentiate between various phonetic features in specific languages. In linguistic studies and language learning materials, U+1D47 is often employed to transcribe words or phrases that include the phoneme /b/ or /p/. Although its usage may be limited compared to more frequently used characters, it remains a valuable tool for accurate representation of phonetic distinctions in various languages and dialects.
