Step 1: Determine the UTF-8 encoding bit layout
The character ⫑ has the Unicode code point U+2AD1. 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+2AD1 to binary:
00101010 11010001. 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 10101011 10010001

Description
The Unicode character U+2AD1, known as CLOSED SUBSET OR EQUAL TO, is a valuable symbol used primarily in mathematical notation and computer programming. Its primary role lies in expressing relationships between sets in digital text, particularly when comparing whether one set is a subset of or equal to another. This character provides a concise way to convey the inclusion-exclusion relationship between two sets within a mathematical context, simplifying complex logical expressions and making them more accessible for both human readers and computer systems. The CLOSED SUBSET OR EQUAL TO symbol is widely used in various fields such as computer science, statistics, and mathematics, contributing significantly to accurate representation of logical statements and set theory concepts.
