Step 1: Determine the UTF-8 encoding bit layout
The character Η has the Unicode code point U+0397. In UTF-8, it is encoded using 2 bytes because its codepoint is in the range of
0x0080to0x07ff.
Therefore we know that the UTF-8 encoding will be done over 11 bits within the final 16 bits and that it will have the format:110xxxxx 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+0397 to binary:
00000011 10010111. 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:
11001110 10010111

Description
U+0397 is the Unicode code point for the Greek capital letter eta (ἠ). In digital text, this character is used to represent the beginning of a word when transcribing from the Ancient Greek alphabet, also known as the Euboeic script. While its usage in modern typography and text formatting has diminished due to the shift towards the Modern Greek alphabet, it remains significant for historical linguistic analysis, translations, and studies of Ancient Greek literature. The eta was originally used as a ligature connecting the previous vowel with an iota subscript (ᵷ), but in modern usage, it stands independently as a capital letter representing the sound /e/ or /ɛ/. In the context of digital typography, U+0397 ensures accurate representation and encoding of this historical Greek character across various platforms and software.
