Step 1: Determine the UTF-8 encoding bit layout
The character ⨷ has the Unicode code point U+2A37. 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+2A37 to binary:
00101010 00110111. 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 10110111

Description
The Unicode character U+2A37, known as the "Multiplication Sign in Double Circle," serves a unique purpose in digital typography. It is primarily used to indicate multiplication in mathematical expressions. Its distinctive design features two concentric circles surrounding an x symbol, which visually distinguishes it from other mathematical symbols and enhances the readability of complex equations. While not as widely used as other mathematical symbols, U+2A37 has found a niche in certain educational contexts and scientific disciplines where clarity is paramount. Its use in digital text ensures that readers can easily identify multiplication operations within equations or calculations.
