Step 1: Determine the UTF-8 encoding bit layout
The character ㆩ has the Unicode code point U+31A9. 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+31A9 to binary:
00110001 10101001. 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 10101001

Description
The Unicode character U+31A9, known as BOPOMOFO LETTER ANN, is a typographic representation used primarily in digital text. It serves as a crucial component of the Bopomofo script, a phonetic writing system developed by Japanese missionaries in Taiwan for transcribing Mandarin Chinese. The character signifies the sound "an" or "ang," depending on its position within a word or syllable. This phonetic system is essential for language learners and linguists as it facilitates pronunciation practice and transcription of Mandarin tones. Despite being less common in mainstream usage, Bopomofo remains culturally significant in certain linguistic contexts, particularly in Taiwanese education and the study of Chinese languages.
