Step 1: Determine the UTF-8 encoding bit layout
The character ἥ has the Unicode code point U+1F25. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800
to0xffff
.
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 thex
are 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+1F25 to binary:
00011111 00100101
. 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 10100101

Description
The Unicode character U+1F25, known as "GREEK SMALL LETTER ETA WITH DASIA AND OXIA," is a specialized typographic symbol used in digital text. It represents the Greek letter eta with diacritical marks - daseia and oxia. In the context of Greek language, these diacritics can alter the pronunciation or meaning of the base character. The daseia mark indicates a long vowel sound, while the oxia mark signifies a rough breathing sound in the following syllable. This specific character is used to maintain historical and linguistic accuracy when transcribing ancient Greek texts or presenting academic content that requires precise representation of classical Greek orthography. In digital text, U+1F25 ensures clarity and faithful rendition of these subtleties for readers and scholars in the fields of Classics, Linguistics, and Ancient History.
