Step 1: Determine the UTF-8 encoding bit layout
The character Ⅲ has the Unicode code point U+2162. 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+2162 to binary:
00100001 01100010. 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 10100010

Description
U+2162 is the Unicode character code for the Roman Numeral Three (Ⅲ). This character is primarily used in digital text to represent the Roman numeral "III" when conveying numerical information that requires the use of traditional Roman numerals. In contrast to Arabic numerals, which are used universally for numerical data and calculations, Roman numerals hold cultural significance and are often employed in contexts such as numbering historical periods, naming events or ceremonies, and representing certain dates or chapters in literature. The use of U+2162 is particularly prominent in works that draw from classical antiquity, ancient history, and the arts, where Roman numerals serve to evoke a sense of timelessness and tradition.
