Step 1: Determine the UTF-8 encoding bit layout
The character ⫄ has the Unicode code point U+2AC4. 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+2AC4 to binary:
00101010 11000100. 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 10000100

Description
The Unicode character U+2AC4, known as the Superset of or Equal to with Dot Above (⊆), is a mathematical symbol commonly used in digital text, particularly within the field of computer science and mathematics. It represents the concept of set inclusion or subset relationship between two sets. This character plays a crucial role in various algorithms and data structures, especially when dealing with binary relationships, such as membership or containment. U+2AC4 is not tied to any specific culture or language, but its usage can be seen in mathematical texts and programming languages worldwide. The dot above the symbol serves as an indicator of a closed or enclosed set, emphasizing that the relationship is fully inclusive. In digital typography, this character contributes to improved readability and clearer communication of complex concepts in mathematical expressions and formulas.
