Step 1: Determine the UTF-8 encoding bit layout
The character ↩ has the Unicode code point U+21A9. 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+21A9 to binary:
00100001 10101001. 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 10000110 10101001

Description
The Unicode character U+21A9, also known as the Leftwards Arrow with Hook, plays a significant role in digital text by serving as a mathematical symbol. It is used to denote the direction of movement in various contexts, such as mathematical equations, computer programming, and physics calculations. In these fields, it represents an action or operation that moves a value or element to the left with a slight rotation. This character provides essential clarity and accuracy in complex equations and algorithms where the direction and orientation of data flow are critical. It is particularly useful in situations where the order of operations needs to be clearly indicated to avoid misinterpretation, such as in the process of reassigning values or navigating through a sequence of steps in an algorithm.
