Step 1: Determine the UTF-8 encoding bit layout
The character 1 has the Unicode code point U+0031. 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+0031 to binary:
00110001. 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+0031, known as DIGIT ONE, plays a significant role in digital text. It is the first digit (1) used in both numerical and alphanumeric contexts. This fundamental component of data representation is essential for numbering systems, coding, and various applications across diverse fields and industries. U+0031 is culturally, linguistically, and technically important due to its basis in the decimal system, a widely employed numeral system worldwide. In numeric representations, it is typically followed by other digits to form whole numbers, such as 12, 100, or 1000. Furthermore, in alphanumeric contexts, it can be combined with uppercase (U+0041) and lowercase (U+0061) alphabetic characters to create unique identifiers or codes. The digit one is part of the Basic Latin Unicode block, encompassing essential characters from U+0000 to U+007F. This range includes a variety of control codes and special symbols that play crucial roles in programming languages, text documents, and digital communication. Despite its historical roots in the ASCII character set, the Basic Latin Unicode block has evolved to accommodate modern needs and remains an integral part of digital communication today.
