Step 1: Determine the UTF-8 encoding bit layout
The character Ⅳ has the Unicode code point U+2163. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800
to0xffff
.
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 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+2163 to binary:
00100001 01100011
. 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 10100011

Description
The Unicode character U+2163, also known as ROMAN NUMERAL FOUR, is a crucial element in digital typography, particularly when dealing with historical texts, mathematics, or ancient Roman numeral systems. This symbol holds significant importance in the study of history and archaeology, as it provides a visual representation of the Roman numeral system used by the Romans from around 753 BC to 14 AD. Unlike its modern counterpart, the Arabic numeral system, which is base-10 and uses unique symbols for each digit (0-9), the Roman numeral system is based on a combination of seven letters from the Latin alphabet, including I, V, X, L, C, D, and M. U+2163 is an invaluable tool for preserving and understanding historical documents, archaeological findings, and ancient manuscripts that employ this unique numeral system. It also serves as a popular typographic choice for creative purposes, such as logo designs, branding, and graphic design elements, owing to its distinct aesthetic appeal and cultural significance.
