Step 1: Determine the UTF-8 encoding bit layout
The character ␕ has the Unicode code point U+2415. 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+2415 to binary:
00100100 00010101. 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 10010101

Description
The Unicode character U+2415 is known as the Symbol for Negative Acknowledge (SNAC). It is predominantly used in digital text communication, particularly in telecommunication protocols and messaging systems. This symbol serves to indicate that a negative acknowledgment has been received or sent. In technical contexts, it is utilized to signify that an operation or command has not been executed successfully or as expected, often indicating a failure or error in the process. The SNAC character plays a vital role in ensuring effective communication and error handling in digital systems, helping to maintain data integrity and prevent miscommunications.
