Step 1: Determine the UTF-8 encoding bit layout
The character ⇠ has the Unicode code point U+21E0. 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+21E0 to binary:
00100001 11100000. 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 10100000

Description
The Unicode character U+21E0, known as the Leftwards Dashed Arrow, is a typographical symbol commonly used in digital text to represent a directional flow or movement towards the left. It is often employed in mathematical expressions, computer science, and engineering fields where arrows are utilized to denote vectors, functions, or processes moving from one point to another along a specific axis. The Leftwards Dashed Arrow stands out for its distinct design, which features a slanted arrowhead with a dashed line tail, setting it apart from other arrow symbols in typography. This unique appearance can be attributed to its Unicode codepoint, U+21E0, which was added in Version 1.1 of the Unicode Standard in 1993.
