Step 1: Determine the UTF-8 encoding bit layout
The character has the Unicode code point U+20F7. 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+20F7 to binary:
00100000 11110111. 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 10000011 10110111

Description
U+20F7 is a character in the Unicode Standard, which represents the "DOUBLE DOWN ARROW" (⇙). In digital text, this symbol is typically used to represent a double rightward arrow pointing downwards, signifying an increase or decrease in value. While its usage may be less common compared to other arrows like the single right-facing arrow (→) or the up-facing arrow (↑), the double down arrow can still serve as a valuable tool for conveying certain directions or actions within text content. U+20F7 is often used in programming, mathematical formulas, and scientific documents to illustrate specific instructions or processes that involve a repeated action moving downwards. This character holds significance in technical contexts where precise communication of movement and direction is crucial.
