Step 1: Determine the UTF-8 encoding bit layout
The character has the Unicode code point U+0007. 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+0007 to binary:
00000111
. 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:
00000111

Description
The Unicode character U+0007 (CHARACTER 0007), also known as the Bell character or the Backspace character, plays a significant role in digital text as a control character. It is primarily used to signal the computer to return the cursor to the previous position and delete the last typed character, a function commonly employed in text editing programs and command line interfaces. In terms of its cultural, linguistic, or technical context, the Bell character has no specific relevance as it serves as a low-level control code rather than a visible symbol or glyph. However, it holds historical importance as one of the first defined characters in the ASCII table and has been instrumental in shaping modern digital communication. Despite being considered obsolete in many contemporary systems due to advancements in programming languages and text editors that now use higher-level commands for cursor manipulation, the Bell character remains an essential part of computer history. It is encompassed within the Basic Latin Unicode block (U+0000 to U+007F), which includes 128 characters vital for programming languages, text documents, and various other applications. This block serves as the foundation upon which many other Unicode blocks are built, showcasing its continued relevance in digital communication despite its historical roots.
