Step 1: Determine the UTF-8 encoding bit layout
The character ⾃ has the Unicode code point U+2F83. 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+2F83 to binary:
00101111 10000011. 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:
11100010 10111110 10000011

Description
The Unicode character U+2F83 represents the "Kangxi Radical Self" (自) in traditional Chinese typography. This radical is used in the classification of characters in dictionaries, particularly those following the Kangxi Dictionary (康熙字典) system. It serves as an organizing principle for categorizing Chinese characters based on their structural components and meaning, rather than a character itself with direct semantic or phonetic significance in digital text. The Kangxi Radical Self is one of 540 radicals used in the classification system, which has been widely employed since the early Qing Dynasty (1644-1912) for better organization and understanding of the vast Chinese language. In modern times, this radical continues to play a vital role in digital text processing, particularly in the context of lexicographical research and Chinese character education.
