Step 1: Determine the UTF-8 encoding bit layout
The character ∗ has the Unicode code point U+2217. 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+2217 to binary:
00100010 00010111. 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 10001000 10010111

Description
The Unicode character U+2217 is known as the Asterisk Operator (∗), and it plays a crucial role in digital text for its versatile applications in mathematics, computer science, and programming. Its primary usage is to denote multiplication or repeated addition, as seen in various mathematical expressions where it signifies the application of an operation multiple times. For example, in the formula 3∗x = 3x, the Asterisk Operator denotes the multiplication of 3 by the variable x. Moreover, U+2217 finds its place within the context of set theory, where it signifies the 'element of' relationship between a set and an element. In linguistic terms, the Asterisk Operator is employed in phonetics to represent a morpheme or a grammatical component that occurs with varying degrees of frequency. In technical contexts, U+2217 serves as a delimiter in regular expressions, a powerful tool for pattern recognition and searching in text processing. Its use in programming languages demonstrates its significance in computational operations, further highlighting the character's widespread utility across various digital domains. Despite not being culturally significant, the Asterisk Operator's applications underline its importance within digital communication, making it an indispensable tool for those who rely on precise and accurate representation of data and concepts in their work.
