Step 1: Determine the UTF-8 encoding bit layout
The character ⊅ has the Unicode code point U+2285. 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+2285 to binary:
00100010 10000101. 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 10000101

Description
The Unicode character U+2285, "⊘", represents the Not A Subset of symbol. This mathematical symbol is commonly used in digital text to indicate that a set is not a subset of another set. It holds importance in both computer science and mathematics, where it is frequently employed in proving concepts and properties related to sets and relations. The U+2285 symbol has no specific cultural or linguistic context but plays a significant role in digital text, particularly within the realm of formal proofs and mathematical notations. By avoiding fluff and focusing on accuracy, this symbol accurately conveys its intended meaning: that one set does not wholly contain another.
