Step 1: Determine the UTF-8 encoding bit layout
The character ϙ has the Unicode code point U+03D9. 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+03D9 to binary:
00000011 11011001. 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:

Description
U+03D9, also known as Greek Small Letter Archaic Koppa, is a rare character primarily used in digital texts for its historical significance. It played a prominent role in the ancient Greek alphabet, serving as the eighth letter. Although not commonly utilized today, it still holds cultural and linguistic importance as a representation of early Greek writing systems. The archaic koppa was replaced by the modern Greek letter sigma (Σ, σ) in later stages of development. Its digital encoding allows for its inclusion in various computer systems and software applications, ensuring its preservation within historical records and academic research.
