Step 1: Determine the UTF-8 encoding bit layout
The character ↫ has the Unicode code point U+21AB. 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+21AB to binary:
00100001 10101011
. 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 10101011

Description
The Unicode character U+21AB, known as the "LEFTWARDS ARROW WITH LOOP", serves a specific role in digital text by representing a leftward arrow that forms a loop. This character is primarily used in mathematical notation and programming contexts to indicate an operation or a function. In mathematical expressions, it can signify that a certain computation should be performed in a loop until a condition is met. Additionally, this character may be employed within the context of computer programming languages, where it can denote a specific type of control flow construct such as a loop or a recursive process. While U+21AB does not have any direct cultural, linguistic, or technical significance, its usage in these contexts is essential for accurate and clear communication of ideas in various fields.
