Step 1: Determine the UTF-8 encoding bit layout
The character ἡ has the Unicode code point U+1F21. 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+1F21 to binary:
00011111 00100001. 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 10111100 10100001

Description
The Unicode character U+1F21, known as "GREEK SMALL LETTER ETA WITH DASIA," holds a significant role in digital text, particularly within the Greek language. It is an alphabetic symbol that represents the Greek letter 'η' (eta) with a dieresis mark or "diaeresis" (the small vertical line beneath the letter). This diacritical mark indicates that the vowel sound should be long, in contrast to when the diaeresis is absent. In linguistic and cultural contexts, the Greek language has historically been of great importance, as it has served as a foundation for many modern languages, including English through Latin. The Unicode character U+1F21 plays a crucial role in maintaining the integrity of the Greek language in digital spaces by ensuring accurate representation and readability of text.
