Step 1: Determine the UTF-8 encoding bit layout
The character ⦲ has the Unicode code point U+29B2. 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+29B2 to binary:
00101001 10110010. 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 10100110 10110010

Description
The Unicode character U+29B2, known as "EMPTY SET WITH SMALL CIRCLE ABOVE," holds a unique role in digital text by representing an empty set with a small circle above it. It is mainly used in mathematical contexts and formulas to denote an empty set or a null set, emphasizing the idea of a collection that contains no elements. In linguistics and culture, this character may not have any specific significance, but its technical usage is crucial for accurate communication of complex concepts and ideas within digital text, particularly in fields like mathematics, computer science, and engineering. Due to its specialized function, the EMPTY SET WITH SMALL CIRCLE ABOVE is an essential tool for clear expression of certain types of information in digital environments.
