Step 1: Determine the UTF-8 encoding bit layout
The character ⩀ has the Unicode code point U+2A40. 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+2A40 to binary:
00101010 01000000. 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 10000000

Description
The Unicode character U+2A40, known as the Intersection with Dot, primarily serves a typographical purpose within digital text. It is an algebraic symbol representing the intersection of two sets or objects, denoted by the capital Greek letter "Xi" (Ξ), and is accompanied by a small dot. This character is particularly useful in mathematical texts and formulae, where it can be used to signify the intersection between two mathematical entities. Although not widely used, the Intersection with Dot holds importance in specific fields such as set theory, graph theory, and other disciplines where the concept of intersection is fundamental. It may also appear in computer programming languages or software applications that require the use of Unicode characters for specialized text representation or formatting.
