Step 1: Determine the UTF-8 encoding bit layout
The character ⇻ has the Unicode code point U+21FB. 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+21FB to binary:
00100001 11111011
. 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 10111011

Description
The Unicode character U+21FB, known as the RIGHTWARDS ARROW WITH DOUBLE VERTICAL STROKE, is a symbol used in digital text to represent an arrow pointing rightwards with two vertical lines bisecting it. This typographic element serves a critical role in mathematical equations and scientific notation, where it denotes an operation or function, often relating to vector spaces or transformations. It is also employed in computer graphics and programming, specifically in data flow diagrams and algorithms that require visual representation of rightward movement with emphasis on directionality. Although this character might appear niche or technical, its versatile application across various fields, such as physics, engineering, and computer science, underscores its significance in modern digital communication.
