Step 1: Determine the UTF-8 encoding bit layout
The character ⮁ has the Unicode code point U+2B81. 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+2B81 to binary:
00101011 10000001. 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 10101110 10000001

Description
The Unicode character U+2B81, known as "UPWARDS TRIANGLE-HEADED ARROW LEFTWARDS OF DOWNWARDS TRIANGLE-HEADED ARROW," is a specialized symbol used in digital text for its unique directional representation. This character provides a distinct visual cue for readers to follow the sequence of actions or instructions, making it highly valuable in various technical and mathematical contexts. In computer programming languages, U+2B81 is often employed to illustrate data flow diagrams, control structures, and algorithms where an upward-facing triangle arrowhead denotes a continuation or looping action while the leftward-pointing part indicates moving backward or revisiting previous instructions. It can also be found in mathematical expressions and equations, particularly in graph theory, where it helps visualize paths, edges, and nodes within a network or graph. Overall, U+2B81 is an essential tool for precise communication of directions, flow, and relationships in digital text across various fields such as computer science, mathematics, and engineering.
