Step 1: Determine the UTF-8 encoding bit layout
The character ὅ has the Unicode code point U+1F45. 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+1F45 to binary:
00011111 01000101
. 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 10111101 10000101

Description
The Unicode character U+1F45 is known as "GREEK SMALL LETTER OMICRON WITH DASIA AND OXIA." In digital text, this symbol represents a modified form of the Greek letter omicron (ο), which is used in Greek orthography. Specifically, it features two diacritics: the daseia and the oxia. The daseia is an ancient horizontal stroke that has been added to the letter as a way of indicating a long vowel sound, while the oxia is a vertical stroke used to differentiate certain words or grammatical cases. In modern usage, this character may be found in typography and text formatting for historical documents, linguistic studies, or cultural works that require accurate representation of ancient Greek texts.
