Step 1: Determine the UTF-8 encoding bit layout
The character ⨧ has the Unicode code point U+2A27. 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+2A27 to binary:
00101010 00100111. 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 10100111

Description
The Unicode character U+2A27, known as the Plus Sign with Subscript Two, serves a specific purpose in digital text. It is utilized to denote an arithmetic operation in which two is subtracted from the quantity indicated by the preceding number or expression. This character finds its application particularly in mathematics and science where subtraction with a constant value of two is a common operation. Its usage facilitates clear and concise communication of such operations, reducing the possibility of misinterpretation. Despite being less commonly encountered than other mathematical symbols, it remains an integral part of the Unicode system, underscoring its importance in digital textual communication where clarity and precision are essential.
