Step 1: Determine the UTF-8 encoding bit layout
The character ⫊ has the Unicode code point U+2ACA. 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+2ACA to binary:
00101010 11001010. 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 10001010

Description
U+2ACA, also known as "SUPERSET OF ABOVE ALMOST EQUAL TO," is a rarely used mathematical symbol in Unicode that represents the concept of a set containing almost all elements of another set with a minor exception. It's primarily employed in digital text and technical documentation related to set theory, computer science, and mathematics. In these contexts, it helps communicate the idea of inclusiveness and near-completeness within a set of values or data. While not widely recognized or utilized in everyday language, U+2ACA serves an essential role in precise communication for professionals working with complex mathematical concepts.
