Step 1: Determine the UTF-8 encoding bit layout
The character ⩉ has the Unicode code point U+2A49. 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+2A49 to binary:
00101010 01001001. 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 10001001

Description
The Unicode character U+2A49, known as "INTERSECTION ABOVE BAR ABOVE UNION", is a specialized typographical symbol with specific roles in digital text. It's used primarily within mathematical and logical contexts to denote an intersection of sets or propositions. In other words, it signifies that two or more elements have common attributes or meet certain conditions simultaneously. For instance, in set theory, if A and B are two sets, the "INTERSECTION ABOVE BAR ABOVE UNION" symbol (⊋) can be used to represent their intersection (A ∩ B). This symbol is part of the Mathematical Operators group in Unicode, which includes a wide range of mathematical symbols and operations. It helps to maintain clarity and consistency in digital text, especially when dealing with complex mathematical expressions or logical statements, ensuring accurate communication among professionals and students alike.
