Step 1: Determine the UTF-8 encoding bit layout
The character ↴ has the Unicode code point U+21B4. 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+21B4 to binary:
00100001 10110100. 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 10110100

Description
The Unicode character U+21B4 represents the "RIGHTWARDS ARROW WITH CORNER DOWNWARDS". This symbol is commonly used in mathematical notation, particularly in computer algorithms, to indicate a specific direction or movement. It is often employed in programming and computational languages like Python and JavaScript to denote the rightward direction with an added downward corner. In some contexts, it's also used in logic and set theory to denote an element being part of another set. The character maintains its importance in typography due to its specificity in indicating movement or containment within digital text. While this symbol doesn't have a significant cultural or linguistic context, it plays a crucial role in the technical world, especially in computer programming and mathematical notations.
