Step 1: Determine the UTF-8 encoding bit layout
The character ↶ has the Unicode code point U+21B6. 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+21B6 to binary:
00100001 10110110. 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 10110110

Description
U+21B6 is the Unicode character code for the Anticlockwise Top Semicircle Arrow. This typographical symbol is primarily used in digital text to represent a directional arrow that points upwards, while also indicating that the movement should be made in an anticlockwise direction around a semicircular path. The character plays a significant role in various technical and scientific fields such as mathematics, engineering, and computer graphics, where it is employed to illustrate rotational motion, angles, and trajectories. It is particularly useful in diagrams and equations that involve rotations, as it accurately conveys the intended direction and movement without ambiguity. Despite not having a direct linguistic context, U+21B6 contributes to the clarity and comprehensibility of technical documents and communications across different languages and cultures that utilize Unicode for text encoding.
