Step 1: Determine the UTF-8 encoding bit layout
The character ㆧ has the Unicode code point U+31A7. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800
to0xffff
.
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 thex
are 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+31A7 to binary:
00110001 10100111
. 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 10100111

Description
The Unicode character U+31A7 represents the Bopomofo letter "onn" (冀), which is used primarily in digital text for transcribing Mandarin Chinese phonetics. It holds a significant role in typography and linguistic studies due to its function as an essential component of the Bopomofo phonetic alphabet, developed during the early 20th century to facilitate learning and teaching of the Chinese language. The character "冀" is derived from the ancient script "匚", which in turn was based on the seal script. While it may not be widely recognized or utilized outside of specific linguistic circles, the Bopomofo letter "onn" remains a valuable tool for those studying or working with Mandarin Chinese phonetics and pronunciation.
