Step 1: Determine the UTF-8 encoding bit layout
The character ↚ has the Unicode code point U+219A. 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+219A to binary:
00100001 10011010. 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 10011010

Description
The Unicode character U+219A, known as the "LEFTWARDS ARROW WITH STROKE", is a mathematical and typographical symbol primarily used in digital text to represent an arrow pointing to the left. This symbol is commonly employed in various fields such as mathematics, physics, computer science, and engineering to denote direction, flow or progression. In mathematical equations and formulas, it is frequently utilized to indicate a change or shift in direction or value. It's also used in data flow diagrams and programmable logic controllers to represent the flow of information or processes. The character U+219A does not have any specific cultural, linguistic, or technical context beyond its role as a general-purpose arrow symbol with an additional horizontal stroke that distinguishes it from other leftward arrows in typography. This unique stroke adds a visual distinction and clarity when the symbol is used in text, improving readability and reducing potential confusion between similar symbols.
