Step 1: Determine the UTF-8 encoding bit layout
The character ㆱ has the Unicode code point U+31B1. 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+31B1 to binary:
00110001 10110001. 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 10110001

Description
The Bopomofo Letter Om (U+31B1) is a pivotal character in the Bopomofo script, which was developed to transcribe Mandarin Chinese into a written form that could be easily learned by speakers of other languages. Its significance primarily lies in its role as a phonetic symbol representing the 'o' sound. The use of Bopomofo script has seen considerable decline with the widespread adoption of the Pinyin Romanization system, but it remains an important part of language learning resources and historical texts. The character U+31B1 is specifically used to depict the vowel sound "o" in syllables and phrases, contributing to its phonetic accuracy and clarity.
