Step 1: Determine the UTF-8 encoding bit layout
The character ⊄ has the Unicode code point U+2284. 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+2284 to binary:
00100010 10000100. 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 10001010 10000100

Description
The Unicode character U+2284, known as "Not A Subset Of," is a logical operator used in mathematical notation and formal logic. It represents the universal set, which includes every element in the set under consideration and no others. In digital text, it is often employed in set theory, combinatorics, and other areas of mathematics that require clear representation of relationships between elements. U+2284's importance lies in its ability to concisely convey that a given set contains all possible members of a particular category, emphasizing the absence of any exclusivity or restrictions on its contents. While it may not be as widely recognized as other mathematical symbols, its specificity and utility make it a valuable tool for mathematicians, logicians, and anyone working with complex systems of categorization.
