Step 1: Determine the UTF-8 encoding bit layout
The character ⨃ has the Unicode code point U+2A03. 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+2A03 to binary:
00101010 00000011. 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 10101000 10000011

Description
The Unicode character U+2A03, known as the N-ARY UNION OPERATOR WITH DOT, is a typographical symbol primarily utilized in digital text. It serves to represent the union of multiple sets or categories within a specific context. In mathematical and computer science terminology, it denotes the union operation in set theory, combining elements from different groups into a single, unified set. This character's inclusion of a dot distinguishes it from other similar symbols, such as U+2A01 (N-ARY UNION OPERATOR) and U+2205 (UNION PLUS), which do not have this visual element. The use of the N-ARY UNION OPERATOR WITH DOT is often seen in digital texts involving mathematical equations, computer programming, and data manipulation. Although it may appear infrequently in comparison to other Unicode characters, its specificity and clarity contribute significantly to accurate communication within these specialized fields.
