Step 1: Determine the UTF-8 encoding bit layout
The character Ⅸ has the Unicode code point U+2168. 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+2168 to binary:
00100001 01101000
. 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 10101000

Description
The Unicode character U+2168 represents the Roman numeral nine, denoted by the symbol "⃚". This digit is used in digital text to represent the numerical value of nine in documents that employ Roman numerals for stylistic or historical purposes. Although less commonly used than Arabic numerals in modern society, Roman numerals hold significant cultural and linguistic importance, especially in the study of ancient history, archaeology, and classical literature. U+2168 plays a vital role in accurately transcribing historical texts, epigraphy, and various technical specifications that require the use of non-Arabic numerals for proper interpretation.
