Step 1: Determine the UTF-8 encoding bit layout
The character ᾙ has the Unicode code point U+1F99. 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+1F99 to binary:
00011111 10011001. 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 10111110 10011001

Description
U+1F99 is the unique code point representing the Greek capital letter Eta with Dasye and Prosesquigraphy (GREEK CAPITAL LETTER ETA WITH DASIA AND PROSGEGRAMMENI) in Unicode. This character plays a significant role in digital text, particularly in typography and linguistics, where it is used to denote the Greek capital letter 'Ε' with additional diacritical marks. The Dasye (horizontal line beneath the character) and Prosesquigraphy (vertical lines extending from the base of the letters) are indicative of the Eta's position in a word or phrase, helping readers discern its function. U+1F99 is particularly useful for text processing systems, as it provides accurate representation and interpretation of the character, ensuring optimal readability and comprehension across various digital platforms.
