Step 1: Determine the UTF-8 encoding bit layout
The character ⩂ has the Unicode code point U+2A42. 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+2A42 to binary:
00101010 01000010. 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 10000010

Description
The Unicode character U+2A42, known as the Union with Overbar (⋃), holds a significant position in digital typography and symbolic mathematics. It is typically used to represent a union of sets in set theory, where the overbar signifies that the union operation has been performed on the sets represented by the characters underneath it. This character is often employed in mathematical notations and equations, particularly in computer science, algebra, and statistics, as well as within digital text and software applications that deal with symbolic computation or require mathematical notation for precise expression. Although the Union with Overbar (⋃) does not have a notable cultural or linguistic context, its role is crucial in representing complex operations within the realm of mathematics, providing clear and concise visual communication of set unions, intersections, and other fundamental concepts.
