Step 1: Determine the UTF-8 encoding bit layout
The character ↣ has the Unicode code point U+21A3. 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+21A3 to binary:
00100001 10100011. 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 10100011

Description
The Unicode character U+21A3, known as the "RIGHTWARDS ARROW WITH TAIL," is a crucial symbol in digital text for its unique role in representing directional arrows with an extended tail at the right end. This specific arrow is significant in mathematical expressions and computer programming, primarily used to illustrate the rightward shift or movement of data in algorithms, loops, and functions. It helps clarify the flow of information and the sequential order in various computational processes. While it does not have a specific cultural, linguistic, or technical context, its usage demonstrates the versatility of Unicode characters and their importance in creating accurate, concise digital communication.
