Step 1: Determine the UTF-8 encoding bit layout
The character ␡ has the Unicode code point U+2421. 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+2421 to binary:
00100100 00100001. 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 10010000 10100001

Description
The Unicode character U+2421, also known as the Delete symbol (DEL), is a critical figure in digital text editing and communication. This symbol plays a vital role in various computing applications, particularly in text editors and word processors. It allows users to delete or remove characters or sections of text, effectively streamlining the writing and editing processes. In Unicode, this character is classified under the "Control Pictures" category, which encompasses characters that represent control functions rather than displayable content. While it might not be as prominently visible as other characters, its presence in digital text is undeniably integral to modern communication and information management.
