Step 1: Determine the UTF-8 encoding bit layout
The character 0 has the Unicode code point U+0030. 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+0030 to binary:
00110000. 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+0030, more commonly known as the "DIGIT ZERO", is a fundamental component of digital text, serving as a crucial element in representing numerical values within base-10 systems. As the foundation for number representation in decimal numeral systems, Zero plays an indispensable role in mathematics, science, finance, and everyday numeric communication. Originating as a symbol for "nothing" or "emptiness", Zero's significance extends beyond cultural and linguistic boundaries, demonstrating its universal importance in modern computing technology, where it underpins the binary system that is essential to digital data storage and processing. Despite its origins dating back thousands of years, this character remains an indispensable tool for numeracy and digital text understanding across multiple platforms and devices. The Unicode character U+0030 falls within the Basic Latin Unicode block, which encompasses 128 essential characters that range from U+0000 to U+007F. This block forms the basis for various other Unicode blocks and is integral to digital communication due to its inclusion of common characters essential for cross-platform and cross-device communication. Although it stems historically from the ASCII character set, the Basic Latin Unicode block has evolved over time to accommodate modern requirements.
