Step 1: Determine the UTF-8 encoding bit layout
The character ∖ has the Unicode code point U+2216. 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+2216 to binary:
00100010 00010110. 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 10001000 10010110

Description
The Unicode character U+2216, also known as the Set Minus symbol (∩ -), holds a vital position in the realm of digital text. This mathematical symbol is primarily used to represent set difference in the field of mathematics and computer science, where it denotes the subtraction of one set from another. It's employed extensively in various programming languages, particularly in those related to data analysis and statistical computing. For instance, it's widely used in Python, R, and SQL. The Set Minus operation is a fundamental concept in the theory of sets, playing a crucial role in understanding and manipulating the relationships between different sets. It's also employed in certain linguistic contexts, such as computational linguistics or language modeling, where it could represent operations on lexical resources like dictionaries or grammars. Despite its technical nature, U+2216 has a rich cultural significance, reflecting the human quest to categorize and understand the world around us through the lens of mathematics and logic.
