Step 1: Determine the UTF-8 encoding bit layout
The character [ has the Unicode code point U+005B. 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+005B to binary:
01011011. 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+005B, also known as the LEFT SQUARE BRACKET ([ ), is a fundamental symbol in digital text communication. This character is commonly used to denote the beginning of a range or a list, particularly in programming languages and markup languages such as HTML and LaTeX. In these contexts, it is often paired with the RIGHT SQUARE BRACKET (] ) to create an inclusive range. For instance, in regular expressions, the LEFT SQUARE BRACKET is used to indicate a character class or set. Despite having no direct cultural or linguistic significance, this symbol plays a crucial role in various digital communication and programming applications due to its clear and concise function. It is part of the Basic Latin Unicode block (U+0000 to U+007F), which is essential for communication across multiple platforms and devices. This block is the foundation upon which many other Unicode blocks are built, as it contains a multitude of common characters that are indispensable for modern digital communication.
