Step 1: Determine the UTF-8 encoding bit layout
The character ↪ has the Unicode code point U+21AA. 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+21AA to binary:
00100001 10101010. 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 10101010

Description
The Unicode character U+21AA, known as the "RIGHTWARDS ARROW WITH HOOK," is a typographical symbol used primarily in mathematical and scientific digital text. This symbol serves to denote an operation or direction in which elements are shifted to the right with a hooked or curved arrowhead. It is particularly useful in representing certain types of logic operations, flowcharts, and algorithms where the direction of the operation includes a loop or iterative process. The character's usage extends across various fields such as computer science, mathematics, and engineering, where it helps to visualize complex operations with ease and clarity. Despite its technical nature, the U+21AA symbol does not have any specific cultural, linguistic, or historical context. Its primary value lies in its ability to provide a concise and accurate representation of certain types of operations within digital text, ensuring precision and minimizing potential for misinterpretation.
