Step 1: Determine the UTF-8 encoding bit layout
The character ᾐ has the Unicode code point U+1F90. 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+1F90 to binary:
00011111 10010000. 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:

Description
The Unicode character U+1F90 represents "GREEK SMALL LETTER ETA WITH PSILI AND YPOGEGRAMMENI." This specific glyph is a variant of the Greek letter eta (uppercase: Η, lowercase: η), which is the eighth letter of the Greek alphabet. In digital text, U+1F90 serves as a typographical element to indicate an eta with psili (a horizontal line over the letter) and ypogeogrammeni (a diacritical mark at the bottom of the letter). This variant is predominantly used in academic and linguistic contexts, particularly in fields such as ancient history, classical studies, and modern Greek language research. The inclusion of psili and ypogeogrammeni on an eta signifies specific phonetic or grammatical features depending on the language and dialect. For instance, in Ancient Greek, the letter with psili represented a long 'e' sound, while in Modern Greek, it represents the palatalized consonant /j/. As such, U+1F90 plays an important role in accurately representing various linguistic aspects of the Greek language and its historical development.
