Step 1: Determine the UTF-8 encoding bit layout
The character ∋ has the Unicode code point U+220B. 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+220B to binary:
00100010 00001011. 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 10001011

Description
U+220B, the "CONTAINS AS MEMBER" character, plays a significant role in digital text by representing the relationship between an element and a set within mathematical notation. This character is commonly used in set theory to denote that an element is part of a specific set. Its typical usage can be found in various fields such as mathematics, computer science, and engineering, where precise communication of relationships among elements and sets is crucial. The CONTAINS AS MEMBER symbol has no notable cultural or linguistic context but is an essential tool in technical contexts involving the representation of mathematical structures, particularly in the aforementioned fields. Its accurate usage contributes to clear and concise communication within these domains.
