Step 1: Determine the UTF-8 encoding bit layout
The character ⾯ has the Unicode code point U+2FAF. 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+2FAF to binary:
00101111 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:
11100010 10111110 10101111

Description
The Kangxi Radical Face (U+2FAF) is a character primarily used in the Kangxi Dictionary, a lexicographical reference work compiled during the reign of the Kangxi Emperor. In digital text, this character serves as an indicator of the semantic meaning of radicals, which are the basic components of Chinese characters. These radicals help to categorize and organize characters for easier lookup in dictionaries and encyclopedias. The Kangxi Radical Face symbolizes the idea of "face" or "countenance," and is commonly used as a phonetic clue when searching for related characters or compounds in classical Chinese texts. It plays a crucial role in maintaining linguistic and cultural context while facilitating efficient text processing and retrieval in digital environments.
