Step 1: Determine the UTF-8 encoding bit layout
The character ㆯ has the Unicode code point U+31AF. 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+31AF to binary:
00110001 10101111. 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 10101111

Description
The Bopomofo letter U+31AF plays a significant role in digital text encoding, specifically within the Unicode system. It represents the sound "aun" in Mandarin Chinese and is commonly used in Bopomofo, a phonetic writing system developed for transcribing Mandarin into the Latin alphabet. Bopomofo script is particularly useful for language learners and non-native speakers attempting to pronounce and understand Mandarin's complex tonal structure. In digital communication, U+31AF enables accurate representation of spoken Mandarin sounds, facilitating translation and cross-cultural dialogue. As part of the Unicode system, it ensures consistent encoding across various platforms, contributing to the globalization of information exchange.
