Step 1: Determine the UTF-8 encoding bit layout
The character ⟱ has the Unicode code point U+27F1. 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+27F1 to binary:
00100111 11110001. 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 10011111 10110001

Description
The Unicode character U+27F1, known as the "DOWNWARDS QUADRUPLE ARROW," is a specialized symbol used in digital text for various purposes within different domains. In mathematical notation, it is employed to represent an operation called "tetration" or "quaternary exponentiation." This operation involves raising a number to a power of the same base four times. For example, using U+27F1 in the equation A^(B^^C) would denote A raised to the power of B, and then that result raised to the power of C, using the same base (4). In programming and computer science, the DOWNWARDS QUADRUPLE ARROW can also be used as a syntactical element or control character in certain languages. It is utilized to denote the "back" function in some text editors and applications, particularly those designed for code editing and management. This allows users to navigate through their files more efficiently. While U+27F1 might not have widespread cultural or linguistic significance, it does hold a unique role within its specific contexts of usage. Its inclusion in the Unicode Standard ensures that digital text can consistently convey complex mathematical or technical concepts across various platforms and programming languages, contributing to the standardization and advancement of computing technology.
