Step 1: Determine the UTF-8 encoding bit layout
The character ⊥ has the Unicode code point U+22A5. 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+22A5 to binary:
00100010 10100101. 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 10001010 10100101

Description
The Unicode character U+22A5 is known as the "UP TACK" and is primarily used in mathematical expressions and scientific notation. It represents the factorial function, which calculates the product of an integer with all the integers below it down to 1. This character is commonly found in programming languages like Python and C++ where it is often used to denote factorials in equations and calculations. Though not widely known, the UP TACK holds significance in mathematical and computational fields due to its ability to streamline complex formulas and improve readability. It has no direct correlation with cultural or linguistic contexts, as its use is primarily technical in nature.
