Step 1: Determine the UTF-8 encoding bit layout
The character ⾙ has the Unicode code point U+2F99. 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+2F99 to binary:
00101111 10011001. 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 10011001

Description
The character U+2F99, known as the Kangxi Radical Shell, holds a significant position in the realm of Unicode typography. Its primary role lies in digital text encoding, specifically within the Chinese character classification system developed by the Qing Dynasty scholar Zhang Yushu during the Kangxi era. The Kangxi Dictionary, the most authoritative source for this classification system, features a total of 214 radicals, with the Shell being one of them. This categorization serves as a useful tool in identifying the constituent parts and meanings of characters, thus facilitating efficient character lookup and learning. In modern digital text processing, the Kangxi Radical Shell is used to maintain this traditional classification system for Chinese characters, which helps preserve cultural heritage and aids in linguistic studies and computer programming involving Unicode text encoding.
