Step 1: Determine the UTF-8 encoding bit layout
The character ∽ has the Unicode code point U+223D. 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+223D to binary:
00100010 00111101. 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 10001000 10111101

Description
The Unicode character U+223D, known as the Reversed Tilde (˜), plays a vital role in digital text by serving as an operator symbol in mathematical notation, specifically representing the reversal of inequality. This means that when it precedes an expression within parentheses, it inverts the sense of the greater-than or less-than signs, making the expression true if and only if the value inside the parentheses is not greater than or not less than the given value. The Reversed Tilde is particularly useful in set theory, where it can help describe properties of elements within a set. While it may not be as commonly used as other Unicode characters, its importance lies in its precise and concise representation in various mathematical contexts, contributing to the accuracy and clarity of digital texts in these fields.
