Step 1: Determine the UTF-8 encoding bit layout
The character : has the Unicode code point U+003A. 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+003A to binary:
00111010
. 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+003A, commonly known as the COLON (:), plays a pivotal role in digital text formatting. This typographical mark is primarily used as a separator between phrases, clauses, or lists, enhancing readability and comprehension. In programming languages, it serves an essential purpose for control structures such as loops and conditionals. The colon has cultural and linguistic significance, particularly in its use in bullet points, citations, and quotations. Its versatility facilitates clear and organized communication across various disciplines, making it an indispensable element of typography and digital text formatting. The character is part of the Basic Latin Unicode block (U+0000 to U+007F), which is a foundational component of the Unicode system, accommodating 128 essential characters that are fundamental for modern communication across multiple platforms and devices. Despite its historical roots in the ASCII character set, the Basic Latin Unicode block has evolved to meet contemporary needs.
