Step 1: Determine the UTF-8 encoding bit layout
The character ↓ has the Unicode code point U+2193. 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+2193 to binary:
00100001 10010011. 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 10010011

Description
The Unicode character U+2193, known as the DOWNWARDS ARROW, plays a significant role in digital text representation. This typographical element is primarily used to indicate a downward direction or movement in mathematical expressions, scientific notations, and various other applications that require arrow symbols for clearer communication. In programming languages and software interfaces, it often serves as an instruction for navigation, denoting the decrease of an input value or the progression towards lower boundaries. While the DOWNWARDS ARROW does not have a specific cultural or linguistic significance, its application is essential in various contexts like coding, physics equations, flowcharts, and data analysis. Overall, this symbol's versatility and importance make it an indispensable asset in modern typography and digital communication.
