Step 1: Determine the UTF-8 encoding bit layout
The character ↢ has the Unicode code point U+21A2. 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+21A2 to binary:
00100001 10100010. 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 10100010

Description
The Unicode character U+21A2, known as the Leftwards Arrow with Tail, plays a significant role in digital text, primarily serving as an arrow symbol used to denote a leftward flow or direction. This typographical element is commonly utilized in mathematical equations, diagrams, and technical documentation, where it represents a reversal or change in direction. The Leftwards Arrow with Tail differs from the standard left-facing arrow (U+2190) in that its tail extends beyond the head, creating a distinct visual cue that signifies an additional element of movement or direction. In various contexts, this character can be used to denote functions, algorithms, and processes where the flow is reversed or diverted from the expected direction. Overall, U+21A2 serves as a vital tool in visual communication for those working within fields requiring precise representation of directions and flows.
