Step 1: Determine the UTF-8 encoding bit layout
The character ⇘ has the Unicode code point U+21D8. 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+21D8 to binary:
00100001 11011000. 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 10011000

Description
The Unicode character U+21D8, known as the South East Double Arrow (⇘), serves a specific purpose within the realm of digital text and typography. This symbol is part of a group of arrows known as "Heading or Top-Bottom" arrows, which are directional indicators used to represent the position of elements in a grid or layout system. The South East Double Arrow points diagonally from top-right to bottom-left, and is often employed in scenarios requiring precise positional guidance, such as flowchart diagrams or graphical user interfaces. Although it doesn't hold significant cultural or linguistic value, the character plays a vital role in various technical contexts where clarity of spatial orientation is crucial.
