Step 1: Determine the UTF-8 encoding bit layout
The character Ϻ has the Unicode code point U+03FA. 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+03FA to binary:
00000011 11111010. 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+03FA represents the Greek capital letter "Σ" or Sigma, commonly known as the Greek Capital Letter San. This symbol holds a significant position in digital text, particularly in mathematical equations and computer science, as it is often used to denote summation in calculus and statistics. In linguistics, Sigma plays an essential role in the Greek alphabet, serving as the 19th letter, and is derived from the Phoenician letter Samek. While it may not be commonly used in everyday typography, its presence contributes to the richness of digital text and communication across various disciplines, especially within fields that require a mathematical or linguistic foundation.
