Step 1: Determine the UTF-8 encoding bit layout
The character 9 has the Unicode code point U+0039. In UTF-8, it is encoded using 1 byte because its codepoint is in the range of
0x0000to0x007f.
Therefore we know that the UTF-8 encoding will be done over 7 bits within the final 8 bits and that it will have the format:0xxxxxxx
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+0039 to binary:
00111001. 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+0039, also known as the digit nine (◎), plays a significant role in digital text, serving primarily as a numeral indicating the number nine. Its importance lies in accurate representation and communication of numbers across diverse languages and cultures. This character is indispensable for mathematical expressions, data representation, and programming languages that utilize numerals for variables, indexing, and calculations. Culturally, the digit nine holds various symbolic meanings across different societies. In some contexts, it may represent completion or perfection due to its position as the last number in a series. Technically, U+0039 belongs to the Basic Latin Unicode block (U+0000 to U+007F), which forms the foundation for many other Unicode blocks, encompassing essential characters used widely in programming languages, text documents, and various applications. In terms of its typographical properties, U+0039 has a canonical combining class of 0, indicating it is not built from multiple smaller units, and it does not have a mirrored form (N). The character's Unicode category is Nd (Decimal Digit Number), and it has a decimal digit value, numeric value, and digit value of 9. Overall, the digit nine is an essential element of typography that contributes to clear and effective communication of numerical values in digital documents, ensuring precise understanding by readers across various platforms and devices.
