Step 1: Determine the UTF-8 encoding bit layout
The character ↭ has the Unicode code point U+21AD. 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+21AD to binary:
00100001 10101101
. 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:

Description
The Unicode character U+21AD, known as the Left Right Wave Arrow, is a versatile symbol used primarily in digital texts for directional and mathematical purposes. Its typical usage involves representing an arrow that changes direction depending on its context, making it particularly useful in computer graphics, diagrams, and mathematical notation. The Left Right Wave Arrow is part of the Mathematical Alphanumeric Symbols block in Unicode, which includes characters specifically designed for use in mathematical expressions. While not as widely used as some other Unicode characters, the Left Right Wave Arrow has found its niche in certain technical and mathematical contexts due to its unique ability to depict a seamless transition or oscillation between two directions.
