Step 1: Determine the UTF-8 encoding bit layout
The character ⼝ has the Unicode code point U+2F1D. 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+2F1D to binary:
00101111 00011101. 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 10111100 10011101

Description
The Unicode character U+2F1D represents the Kangxi Radical Mouth, a fundamental component of Chinese characters used in traditional Chinese typography. As one of the 560 radicals outlined by the Qing Dynasty scholar Yang Wenhui in his work "Kangxi Zidian," it serves as a reference for understanding and classifying characters. U+2F1D is primarily used in digital text to help users recognize or search for Chinese characters based on their radical compositions, simplifying character identification and improving communication efficiency. In this context, the Kangxi Radical Mouth plays an essential role in preserving and promoting traditional Chinese culture, as well as facilitating language education and computational linguistics research.
