Step 1: Determine the UTF-8 encoding bit layout
The character ⇚ has the Unicode code point U+21DA. 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+21DA to binary:
00100001 11011010. 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 10011010

Description
The Unicode character U+21DA, known as the Leftwards Triple Arrow, plays a significant role in digital text. It is primarily used to indicate reversal or backtracking in various contexts, such as programming and mathematical expressions. Notably, it is frequently utilized in algorithms and data structures like stacks and queues to denote the "pop" operation. This character also finds application in graph theory and network analysis, representing an edge or path that leads back to a previous point. Despite its technical nature, the Leftwards Triple Arrow holds no specific cultural, linguistic, or artistic significance. Its primary function remains within the realm of precise digital communication and computation, making it an indispensable tool for professionals in various technical fields.
