Step 1: Determine the UTF-8 encoding bit layout
The character ⺁ has the Unicode code point U+2E81. 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+2E81 to binary:
00101110 10000001. 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 10111010 10000001

Description
The Unicode character U+2E81 represents the "CJK Radical Cliff" (also known as Chinese character radical 水, in Simplified Chinese). This character is an essential part of the Chinese writing system and has been widely used for centuries to categorize and structure Chinese characters. In the context of digital text, it serves as a reference for students, educators, and researchers to understand the fundamental components and meanings of complex characters. U+2E81 belongs to the CJK Extensions C Unicode block, which comprises additional radicals used in Chinese character composition. The character is primarily used in East Asian countries where Chinese characters are utilized, including China, Taiwan, Japan, and Korea, making it an important part of their linguistic and cultural heritage.
