Step 1: Determine the UTF-8 encoding bit layout
The character ⇝ has the Unicode code point U+21DD. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800
to0xffff
.
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 thex
are 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+21DD to binary:
00100001 11011101
. 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 10011101

Description
The Unicode character U+21DD, known as the RIGHTWARDS SQUIGGLE ARROW, is a typographical symbol used in digital text to represent a rightward squiggle. It serves as an arrow that curls back upon itself, creating a more fluid and less linear directional indication than traditional straight arrows. This symbol is commonly utilized in mathematical and scientific notation, where it can be employed to depict various concepts such as derivatives, integrals, or the behavior of functions. Its unique squiggle shape sets it apart from other arrow symbols, making it an essential tool for conveying specific ideas within these contexts. While it may not have a direct cultural or linguistic significance, its use in technical domains speaks to the diversity and expressiveness of Unicode's extensive character set.
