Step 1: Determine the UTF-8 encoding bit layout
The character ⨄ has the Unicode code point U+2A04. 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+2A04 to binary:
00101010 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 10101000 10000100

Description
U+2A04, the N-ary Union Operator with Plus, is a rare character in Unicode, primarily used to represent set union operations in mathematical expressions and digital text. In specific scenarios involving multiple sets, this operator denotes that all elements within each set should be combined into a single comprehensive set while also accounting for any additional unique elements present. While its use may not be as widespread or commonplace as other Unicode characters, it holds importance in specialized fields such as computer science and mathematical notation. The N-ary Union Operator with Plus contributes to the precision and clarity of expressions involving complex sets, ensuring accurate communication of intricate concepts and relationships.
