Step 1: Determine the UTF-8 encoding bit layout
The character Ⅰ has the Unicode code point U+2160. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800to0xffff.
Therefore we know that the UTF-8 encoding will be done over 16 bits within the final 24 bits and that it will have the format:1110xxxx 10xxxxxx 10xxxxxx
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+2160 to binary:
00100001 01100000. 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:
11100010 10000101 10100000

Description
The Unicode character U+2160, known as the Roman Numeral One, holds a significant role in digital typography. It is commonly utilized to represent the number one within the Roman numeral system. This numeral system predates the Arabic numerals we use today and was prevalent throughout ancient Rome. The Roman Numeral One (U+2160) finds its application primarily in academic, historical, and cultural contexts where the Roman numeral system is employed for illustrative or stylistic purposes. It can also be encountered in coding, programming, and digital text formatting to demonstrate numerical representations that deviate from conventional Arabic numerals. The use of U+2160 underscores the versatility and richness of Unicode's character set, which accommodates a wide array of global typographical conventions.
