Step 1: Determine the UTF-8 encoding bit layout
The character ⋑ has the Unicode code point U+22D1. 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+22D1 to binary:
00100010 11010001. 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 10010001

Description
The Unicode character U+22D1 represents the Double Superset symbol. This mathematical symbol is typically used in digital text to denote a relationship between two sets, indicating that one set is a superset of another. It is often employed in fields such as computer science, mathematics, and data analysis to demonstrate the inclusion of one set within another. The Double Superset symbol serves a crucial role in clarifying the hierarchical relationships among sets in various mathematical, logical, and computational contexts.
