Step 1: Determine the UTF-8 encoding bit layout
The character ↠ has the Unicode code point U+21A0. 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+21A0 to binary:
00100001 10100000
. 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 10100000

Description
The Unicode character U+21A0, known as the Rightwards Two-Headed Arrow (↝), is a symbol commonly used in digital text to represent simultaneous bi-directional movement or transformation. It holds a critical role in mathematical equations, particularly those involving vector analysis and complex algebra, where it signifies a change in both magnitude and direction at the same time. In the field of computer science, this character is frequently encountered in algorithms and programming languages that deal with graphical elements, data flow, or process control. The symbol does not have any specific cultural, linguistic, or technical context beyond its mathematical and algorithmic applications. Its usage is primarily functional, ensuring accurate representation of bi-directional processes and interactions.
