Step 1: Determine the UTF-8 encoding bit layout
The character ⊈ has the Unicode code point U+2288. 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

Convert the hexadecimal code point U+2288 to binary:
00100010 10001000. 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:

Description
The Unicode character U+2288, known as "NEITHER A SUBSET OF NOR EQUAL TO" (⊈), plays a significant role in digital text by representing the logical negation of subset and equality relationships within mathematical equations and set theory. It is commonly employed in formal proofs and logical arguments to express the concept that a specific set or object does not fall under a particular category or satisfy certain conditions, thus emphasizing the distinction between two entities or properties. The character's usage is grounded in linguistic and cultural contexts where mathematical notation and symbolism are prevalent, such as in academic texts, scientific literature, and computer programming. By providing an accurate and concise representation of this logical relationship, U+2288 contributes to the clarity and precision of digital text within these contexts.
