Step 1: Determine the UTF-8 encoding bit layout
The character ∄ has the Unicode code point U+2204. 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+2204 to binary:
00100010 00000100. 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 10001000 10000100

Description
The Unicode character U+2204, known as "THERE DOES NOT EXIST", is a typographical symbol used predominantly in mathematical notation and formal logic. In digital text, it signifies the negation of existence or the absence of an element within a specific set. This character finds its application primarily in proofs, algorithms, and logical arguments where the concept of non-existence or exclusivity needs to be clearly conveyed. While not widely used in everyday language, it holds significant importance in specialized fields such as computer science, mathematics, and formal logic.
