Step 1: Determine the UTF-8 encoding bit layout
The character ⽏ has the Unicode code point U+2F4F. 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+2F4F to binary:
00101111 01001111. 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 10111101 10001111

Description
The Unicode character U+2F4F, known as "KANGXI RADICAL DO NOT," is a specialized typographic symbol primarily used in the Chinese language system. In digital text, it serves as a visual marker to indicate that a specific character or sequence of characters should not be used in a given context. This is especially important when working with traditional Chinese characters and their radical components. The KANGXI RADICAL DO NOT character is derived from the Kangxi Dictionary, one of the most comprehensive dictionaries of the Chinese language, compiled by Emperor Kangxi during the Qing Dynasty. It reflects the rich history and cultural significance of Chinese typography, highlighting the importance of proper usage and understanding of characters in this ancient writing system.
