Step 1: Determine the UTF-8 encoding bit layout
The character ⋽ has the Unicode code point U+22FD. 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+22FD to binary:
00100010 11111101. 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 10111101

Description
The Unicode character U+22FD represents the mathematical symbol "contains with overbar". This symbol is often used in set theory to denote that one set contains another set. In digital text, it is used primarily in mathematics, computer science, and engineering fields where set notation is common. Its usage is essential in representing relationships between sets, such as subsets and supersets, which are fundamental concepts in many mathematical disciplines like algebra, topology, and logic. The overbar also has applications in physics and chemistry to represent isotopes or compound molecules. Although it doesn't have any specific cultural or linguistic significance, its usage is globally recognized due to its widespread application in various scientific and technical domains. Its accurate representation depends on the font being used, as some may display the overbar above the entire set symbol, while others might only show it over the letters of the contained set.
