Step 1: Determine the UTF-8 encoding bit layout
The character ⤙ has the Unicode code point U+2919. 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+2919 to binary:
00101001 00011001
. 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 10100100 10011001

Description
The Unicode character U+2919, known as the "LEFTWARDS ARROW-TAIL" (←), plays a significant role in digital text representation. It is primarily used to indicate a leftward direction or movement, serving as a crucial element in various mathematical notations, programming languages, and typography systems. In mathematical contexts, it is often employed in vector algebra to represent the cross product of two vectors. In programming, it signifies the "left shift" operator that shifts bits of a number to the left. The LEFTWARDS ARROW-TAIL character also finds application in arrow diagrams for flowcharts and state transition tables. While there is no specific cultural or linguistic context associated with this character, its universal usage across languages and platforms underscores its importance in digital text communication and representation.
