Step 1: Determine the UTF-8 encoding bit layout
The character ⋃ has the Unicode code point U+22C3. 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+22C3 to binary:
00100010 11000011. 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 10001011 10000011

Description
The character U+22C3, known as the N-ary Union symbol, is a vital element in mathematical notation and digital text. This symbol, often used in set theory, represents the union of an arbitrary number (n) of sets. It signifies that all elements from the individual sets are combined into one comprehensive set without any duplication. The N-ary Union symbol is particularly significant in computational mathematics and computer science, where it helps define operations on data structures such as arrays, lists, or tuples. In programming languages like Python and Haskell, this symbol can be found in the form of "∪", demonstrating its widespread use across various digital platforms. However, despite its importance, the N-ary Union symbol is not commonly seen in everyday language, being primarily confined to technical and academic contexts where precise mathematical notation is crucial.
