Step 1: Determine the UTF-8 encoding bit layout
The character ⇛ has the Unicode code point U+21DB. 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+21DB to binary:
00100001 11011011. 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 10011011

Description
The Unicode character U+21DB represents the RIGHTWARDS TRIPLE ARROW. It is a directional symbol used primarily in mathematical equations to indicate the movement of vectors in digital text. This glyph holds significant importance in fields such as physics, computer science, and engineering where vector calculations are prevalent. The RIGHTWARDS TRIPLE ARROW is often employed in conjunction with other arrows like UPWARDS SINGLE ARROW (U+2191) and DOWNWARDS DOUBLE ARROW (U+21D3) to represent various movements and directions. Its inclusion in the Unicode Standard ensures consistency and compatibility across different software applications and programming languages, thus enhancing readability and comprehension of mathematical expressions globally.
