Step 1: Determine the UTF-8 encoding bit layout
The character Ϲ has the Unicode code point U+03F9. 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+03F9 to binary:
00000011 11111001. 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+03F9, known as the Greek Capital Lunate Sigma Symbol, plays a significant role in digital text, particularly within the realm of mathematics and computer science. This symbol is derived from the Greek alphabet, specifically the letter sigma (Σ). It has been adopted to represent the concept of summation or sum in mathematical notation. In this context, it is often employed as an alternative to the more commonly used Latin-based symbols, such as S for summation or the sigma character with a dot underneath, which are also part of Unicode (U+1D4B6). The use of U+03F9 allows for greater typographical consistency and cultural authenticity in digital texts that require Greek letters for their content. As a result, it has found its place in various fields, including mathematics, computer science, linguistics, and historical studies.
