Step 1: Determine the UTF-8 encoding bit layout
The character Ἧ has the Unicode code point U+1F2F. 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+1F2F to binary:
00011111 00101111. 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 10101111

Description
The Unicode character U+1F2F, known as the "Greek Capital Letter Eta with Dasi and Perispomeni," plays a significant role in digital text, particularly within the realm of ancient Greek studies. This character is a part of the broader Unicode system, which aims to standardize the representation of characters from different writing systems across various platforms and applications. The U+1F2F is used to represent an archaic form of the Eta letter in ancient Greek texts, specifically those that date back to the Archaic period (800-480 BCE). It features two additional diacritical marks, the Dasi (ῂ) and Perispomeni (ῃ), which were used in ancient Greek writing to modify the pronunciation of vowels. Today, the U+1F2F is primarily used by researchers, classicists, and linguists who work with ancient texts, providing them with an accurate digital representation of this unique aspect of ancient Greek typography. This character reflects the rich cultural and linguistic heritage of ancient Greece while also serving as a technical tool for scholars in their analysis and interpretation of these historical documents.
