Step 1: Determine the UTF-8 encoding bit layout
The character + has the Unicode code point U+002B. 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+002B to binary:
00101011. 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:
00101011

Description
The Unicode character U+002B, commonly known as the Plus Sign (+), holds significant importance within digital text due to its wide-ranging applications. In mathematical equations and computational contexts, it is primarily used to denote addition, serving as a fundamental operator in arithmetic and algebraic expressions across various domains. Beyond numeric operations, the Plus Sign also plays a vital role in diverse technical disciplines such as programming languages and markup languages like HTML and XML. In these technical spheres, the Plus Sign is utilized for numerous purposes, including concatenation of strings, specifying positive integers in loops, and defining relationships between elements or attributes. Although predominantly associated with numeric operations, the Plus Sign's versatility and ubiquity across multiple domains underscore its significance within digital text processing and communication. The Plus Sign belongs to the Basic Latin Unicode block, which encompasses 128 essential characters spanning from U+0000 to U+007F. This range includes control codes and special symbols that play indispensable roles in programming languages, text documents, and various other applications. The Basic Latin Unicode block is the foundation upon which many other Unicode blocks are built, as it contains a multitude of common characters essential for communication across multiple platforms and devices. Despite its historical roots in the ASCII character set, the Basic Latin Unicode block has evolved to accommodate modern needs and continues to be an integral part of digital communication.
