Step 1: Determine the UTF-8 encoding bit layout
The character ⩈ has the Unicode code point U+2A48. 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+2A48 to binary:
00101010 01001000. 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 10101001 10001000

Description
U+2A48, or the "Union Above Bar Above Intersection" character, is a specialized typographical symbol primarily employed in mathematical and engineering texts to denote set-theoretic operations. Its typical usage involves representing the concept of a union followed by an intersection between two sets. In digital text, this Unicode character provides clarity and accuracy when expressing complex relationships and structures within mathematical equations or logical constructs. The Union Above Bar Above Intersection symbol is particularly useful in fields such as computer science, engineering, and statistics where precise communication of set operations is essential. It helps to avoid confusion between different types of logical operations and ensures that readers can accurately interpret the intended meaning of complex expressions.
