Step 1: Determine the UTF-8 encoding bit layout
The character has the Unicode code point U+007F. In UTF-8, it is encoded using 1 byte because its codepoint is in the range of
0x0000
to0x007f
.
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 thex
are 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+007F to binary:
01111111
. 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:
01111111

Description
U+007F, commonly known as the DELETE character, plays a vital role in digital text as a control character within data transmission and communication protocols. This character indicates an error or the need for removal of part of a message during data transfer, ensuring smooth interactions between devices and maintaining the integrity of transmitted information. Although not visible in human-readable text, its significance lies in the realm of modern computing systems. The DELETE character belongs to the Basic Latin Unicode block (U+0000 to U+007F), which encompasses essential characters for programming languages, text documents, and various other applications across multiple platforms. This foundational Unicode block has roots in the ASCII character set but continues to evolve to meet modern needs. In terms of cultural or technical context, the DELETE character is an indispensable element of computing systems, particularly within data communication protocols where its role in error handling and message correction is paramount. Its presence underscores the importance of control characters in maintaining the seamless functioning of digital devices and networks.
