Step 1: Determine the UTF-8 encoding bit layout
The character ἣ has the Unicode code point U+1F23. 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+1F23 to binary:
00011111 00100011
. 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 10100011

Description
The Unicode character U+1F23, known as the "Greek Small Letter Eta with Dasia and Varia," is a specialized symbol used in typography for Greek text. In digital text, it primarily serves a functional role, representing an elongated form of the lowercase letter eta (η), which is the fifth letter of the Greek alphabet. This particular character combines the eta with dasia and varia, two historical features of the ancient Greek script. Dasia refers to the diagonal stroke used in some letters to indicate a long vowel sound, while varia represents an alternate form of a letter that has been modified for specific stylistic or linguistic purposes. The Unicode character U+1F23 is typically used in digital text for typesetting purposes, enabling the accurate representation of historical Greek texts or providing a visually distinct alternative to standard letters in modern typography projects. It is not widely used in everyday language, but rather serves as a specialized tool for those working with ancient Greek script or studying its history and development.
