Step 1: Determine the UTF-8 encoding bit layout
The character ầ has the Unicode code point U+1EA7. 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+1EA7 to binary:
00011110 10100111. 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 10111010 10100111

Description
U+1EA7, also known as Latin Small Letter A with Circumflex and Grave, is a unique character in the Unicode Standard that combines both the circumflex (^) and grave (´) diacritical marks with the lowercase letter 'a'. This character is primarily used in digital text to represent an accented 'a' in certain linguistic contexts. In French, it is known as "à" and signifies a nasalized vowel sound. Its usage can be observed in various languages that employ diacritical marks for phonetic distinctions or to indicate grammatical features such as conjugation and declension. While its use may not be widespread in everyday digital communication, it remains an essential tool for maintaining accuracy and clarity in specialized texts, particularly within linguistic, cultural, and historical contexts where accents play a significant role in meaning and pronunciation.
