Step 1: Determine the UTF-8 encoding bit layout
The character ộ has the Unicode code point U+1ED9. 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+1ED9 to binary:
00011110 11011001. 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:
11100001 10111011 10011001

Description
U+1ED9 (LATIN SMALL LETTER O WITH CIRCUMFLEX AND DOT BELOW) is a unique Unicode character that combines the circumflex accent, often used in French to indicate nasalization or a change in pronunciation, with the dot below accent. This combination of diacritics typically plays a significant role in digital text by enhancing readability and providing precise phonetic information. It is mostly used in specialized dictionaries, language learning materials, and texts that require accurate phonetic representation. Although not as widely adopted as individual circumflex or dot below accents, this character's presence demonstrates the richness of Unicode in accommodating diverse orthographic needs across languages and contexts.
