Step 1: Determine the UTF-8 encoding bit layout
The character ∍ has the Unicode code point U+220D. 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+220D to binary:
00100010 00001101. 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 10001101

Description
The Unicode character U+220D, known as the "SMALL CONTAINS AS MEMBER" symbol, is a mathematical notation used primarily in digital text to represent the concept of subset inclusion. It is typically utilized within the scope of set theory and computer science, where it denotes that one set (or group) contains all elements of another set as members. This character plays an essential role in mathematical expressions, algorithms, and formal logic systems, facilitating a clear and concise representation of relationships between sets. Despite its technical nature, U+220D holds significant cultural and linguistic relevance within the academic community, particularly in the fields of mathematics, computer science, and information technology.
