Step 1: Determine the UTF-8 encoding bit layout
The character ⊊ has the Unicode code point U+228A. 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+228A to binary:
00100010 10001010. 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 10001010 10001010

Description
The Unicode character U+228A, known as SUBSET OF WITH NOT EQUAL TO, plays a significant role in mathematical notation and digital text. This symbol is commonly used to express the concept of a subset that does not include every element of another set. In essence, it denotes a part of a whole that is not equal or identical to the entirety. The SUBSET OF WITH NOT EQUAL TO character finds widespread application in various mathematical disciplines and within computer programming languages that require precise representation of mathematical symbols and relationships. Although it does not have any specific cultural, linguistic, or technical context, its importance lies in facilitating clear communication of complex ideas in fields such as set theory, algebra, and logic. By accurately representing these concepts, U+228A contributes to the clarity and precision of digital text across multiple disciplines.
