Step 1: Determine the UTF-8 encoding bit layout
The character ⅳ has the Unicode code point U+2173. 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+2173 to binary:
00100001 01110011. 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 10110011

Description
U+2173, the SMALL ROMAN NUMERAL FOUR character, is a typographical representation of the Roman numeral for the number four in Unicode. Its typical usage is found within digital text, specifically in mathematical equations and historical documents. The SMALL ROMAN NUMERAL FOUR holds cultural significance as it is derived from ancient Rome's numerical system, which predated Arabic numerals. In typography, this character can be utilized for stylistic purposes or to maintain historical accuracy in texts that involve Roman numerals. Its use has become less common with the widespread adoption of Arabic numerals but remains an important tool for understanding and preserving the history of numerical systems.
