Step 1: Determine the UTF-8 encoding bit layout
The character Ἡ has the Unicode code point U+1F29. 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+1F29 to binary:
00011111 00101001. 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 10101001

Description
The character U+1F29, Greek Capital Letter Eta with Diasia (Ξ), is a unique symbol within the Unicode standard that holds both historical and typographical significance. In digital text, this character serves as an uppercase representation of the Greek letter eta (η). It features a distinct diasia mark, a horizontal stroke across the top bar of the Eta, which distinguishes it from other similar-looking characters in the Greek alphabet. This particular stylistic trait is believed to have originated during the medieval period, when scribes added diasias to certain letters to indicate long vowels or specific sounds in the Byzantine Greek language. Today, the Greek Capital Letter Eta with Diasia (Ξ) plays a crucial role in digital typography and text encoding, as it ensures accurate representation of ancient and modern Greek texts. It is widely used in linguistic research, historical documents, and digital humanities projects to maintain the integrity of original manuscripts and inscriptions. By incorporating U+1F29 into their work, scholars, translators, and enthusiasts can preserve the rich cultural and linguistic heritage of the Greek language while adhering to modern typographic standards and technologies.
