Step 1: Determine the UTF-8 encoding bit layout
The character ⇵ has the Unicode code point U+21F5. 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+21F5 to binary:
00100001 11110101. 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 10000111 10110101

Description
The Unicode character U+21F5 represents the "DOWNWARDS ARROW LEFTWARDS OF UPWARDS ARROW" symbol in typography. This mathematical symbol is primarily used in digital text for expressing a specific type of composition in algebraic equations, specifically to denote the composition of functions in reverse order. For instance, if f(x) and g(x) are two functions, the notation "f ⇾ g" would mean that we are considering the function g before f when performing compositions. The U+21F5 character is part of the Miscellaneous Technical category within the Unicode Standard, which comprises symbols and characters used in various technical fields such as mathematics, science, and technology. Its usage is mostly confined to these disciplines where it helps convey precise mathematical expressions and computations. The U+21F5 character may not have significant cultural or linguistic relevance beyond its utilization in the aforementioned contexts, making it an important tool for clarity and accuracy within technical documentation and communication.
