Step 1: Determine the UTF-8 encoding bit layout
The character ≗ has the Unicode code point U+2257. 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+2257 to binary:
00100010 01010111. 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 10001001 10010111

Description
The Unicode character U+2257, known as "RING EQUAL TO," serves a vital function in mathematical expressions within digital text. It is utilized to represent an inequality relation in mathematical notation systems. Specifically, the RING EQUAL TO symbol represents an imbalance in a mathematical expression and denotes that one side of the equation is not equal to the other. This character is particularly useful for illustrating relationships between values or entities where equality does not hold true. In the realm of digital typography, U+2257 is frequently employed in various programming languages, scientific documents, and mathematical texts to accurately convey the sense of inequality.
