Step 1: Determine the UTF-8 encoding bit layout
The character ⪿ has the Unicode code point U+2ABF. 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+2ABF to binary:
00101010 10111111
. 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 10101010 10111111

Description
The Unicode character U+2ABF, known as "SUBSET WITH PLUS SIGN BELOW," is a typographic symbol used primarily in digital text for mathematical and scientific notation. This character serves a crucial role in expressing set theory, specifically subsets with an added plus sign below them. In the realm of mathematics, it is often employed to represent the concept of a subset that is the result of adding an additional element or elements from another set. It also finds application in linguistics and computer science for representing specific character relationships and interactions. This symbol ensures accurate communication of these concepts by providing a clear visual representation, thereby enhancing readability and understanding in technical contexts where precision matters most.
