Step 1: Determine the UTF-8 encoding bit layout
The character ⋭ has the Unicode code point U+22ED. 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+22ED to binary:
00100010 11101101. 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 10101101

Description
The Unicode character U+22ED, denoted as "⊉", is a mathematical symbol known as "does not contain as normal subgroup or equal." This symbol is mainly used in digital text to represent an algebraic expression that signifies the non-inclusion of a normal subgroup or equality. It is typically employed within mathematical formulas, particularly in set theory and group theory, which are branches of abstract mathematics dealing with sets and groups respectively. While U+22ED might not have a direct cultural or linguistic significance, its usage is crucial in precise communication of complex mathematical concepts. As an expert in Unicode and typography, it's essential to recognize the importance of such symbols in maintaining accuracy and clarity within digital text, especially when discussing advanced topics in mathematics.
