Step 1: Determine the UTF-8 encoding bit layout
The character has the Unicode code point U+0003. 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+0003 to binary:
00000011. 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:
00000011

Description
The Unicode character U+0003, also known as the "Group Separator" or "Control Character," plays a significant role in digital text processing. As one of the control characters defined in ASCII, a subset of Unicode, it provides a common system for representing text in computers. Its typical usage can be seen in communication protocols where it acts as a delimiter to ensure data integrity during transmission between systems. This character, although not directly visible like other alphanumeric or symbol characters, is essential behind the scenes when text is processed, separating different groups in data streams and controlling the flow of information. Its critical role in digital communication often goes unnoticed due to its non-printable nature in visual content, but its influence cannot be overstated. The Unicode character U+0003 belongs to the Basic Latin Unicode block, which encompasses essential characters that span from U+0000 to U+007F. This range includes a wide variety of characters, such as control codes and special symbols, that are indispensable for communication across multiple platforms and devices. The basic Latin Unicode block is the foundation upon which many other Unicode blocks are built, making it an integral part of digital communication. Despite its historical roots in the ASCII character set, the Basic Latin Unicode block has evolved to accommodate modern needs.
