Step 1: Determine the UTF-8 encoding bit layout
The character ⩃ has the Unicode code point U+2A43. 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+2A43 to binary:
00101010 01000011. 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 10101001 10000011

Description
The Unicode character U+2A43, known as "INTERSECTION WITH OVERBAR," primarily serves a mathematical purpose in digital text. It is used to represent the set intersection with an overbar in mathematical expressions, denoting the intersection of two or more sets while visually separating them from the surrounding content. This character is particularly useful in set theory and other mathematical disciplines, where it helps to clarify relationships between different elements within a given context. The INTERSECTION WITH OVERBAR character has no notable cultural, linguistic, or technical context beyond its specific role in mathematics, making it a specialized tool for those working with set theory, statistics, and other related fields.
