Step 1: Determine the UTF-8 encoding bit layout
The character 4 has the Unicode code point U+0034. 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+0034 to binary:
00110100. 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:
00110100

Description
The Unicode character U+0034, commonly known as the digit four (char: 4, code: 52), is a fundamental element in the digital world, widely used for representing numerical data across various applications. This versatile symbol serves numerous purposes beyond mere numbering, including formatting and mathematical equations, due to its universally recognized symbolism that transcends cultural, linguistic, and technical boundaries. As a key component of the base-10 numeric system, digit four has profound implications in counting, measuring, and quantification tasks, structuring the logic of many computational systems. Its importance extends beyond day-to-day calculations, underpinning the foundation of complex algorithms, statistical analysis, and data modeling. The digit four is part of the Basic Latin Unicode block (id: 677), which contains essential characters from U+0000 to U+007F, including control codes and special symbols vital for programming languages, text documents, and other applications. This foundational block supports numerous other Unicode blocks and plays a crucial role in digital communication across multiple platforms and devices. Despite its historical roots in the ASCII character set, the digit four and the Basic Latin Unicode block have evolved to meet modern needs while preserving their original significance. Its indispensable nature in our increasingly digitalized world is evident as it continues to play a pivotal role in shaping the way we interact with data and information.
