Step 1: Determine the UTF-8 encoding bit layout
The character Ϟ has the Unicode code point U+03DE. 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+03DE to binary:
00000011 11011110. 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
The Unicode character U+03DE is the Greek letter Koppa (ϰ), which holds a significant place in typography and historical linguistics. In modern digital text, its usage is quite limited compared to other Greek letters, primarily found in ancient texts, specifically within the ancient Greek alphabet. Koppa's distinct cultural context comes from its historical role in the early stages of the Greek language development, being the 11th letter of the original Phoenician and pre-Alexandrian Greek alphabets. However, by the time of the Alexandrian reform led by Demetrius of Phaleron in the 4th century BC, it was dropped from the main body of the alphabet but continued to be used in certain regions and scripts such as the Old Macedonian script. In terms of technical context, Koppa's Unicode designation (U+03DE) signifies its encoding in digital systems for accurate representation across various platforms and devices. Despite its archaic usage in modern languages, it remains an essential part of typography studies and classical Greek literature exploration.
