Step 1: Determine the UTF-8 encoding bit layout
The character ⫏ has the Unicode code point U+2ACF. 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+2ACF to binary:
00101010 11001111. 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 10101011 10001111

Description
The Unicode character U+2ACF, known as the "CLOSED SUBSET" symbol, is an essential typographic element in digital text, particularly within mathematical and computer science contexts. It represents a closed subset of a given set or collection, indicating that all elements within the specified range fall within the boundaries of the depicted subset. This character provides clarity when discussing concepts such as ranges, intervals, and sets in various fields like mathematics, programming, and data analysis. The CLOSED SUBSET symbol has no specific cultural, linguistic, or regional associations, but it serves a vital role in ensuring precise communication within its technical contexts.
