Step 1: Determine the UTF-8 encoding bit layout
The character ㆿ has the Unicode code point U+31BF. 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+31BF to binary:
00110001 10111111. 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:
11100011 10000110 10111111

Description
The Unicode character U+31BF, known as the Bopomofo Letter AH, is a crucial element within the Bopomofo script system used in the Pinyin romanization of Mandarin Chinese. It has a vital role in digital text as it helps facilitate the representation and phonetic transcription of Chinese characters into an alphabetical format for non-Mandarin speakers. The character AH is part of the Bopomofo script, which was developed during the early 20th century to improve literacy in China by providing a phonetic transcription of Chinese characters, making it easier for those learning Mandarin or trying to pronounce unfamiliar terms. U+31BF plays a significant cultural, linguistic, and technical role by bridging the gap between speakers of different languages who wish to communicate using the vast array of Chinese vocabulary.
