Step 1: Determine the UTF-8 encoding bit layout
The character ϲ has the Unicode code point U+03F2. 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+03F2 to binary:
00000011 11110010. 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+03F2 represents the Greek Lunate Sigma Symbol (Γ). This unique symbol is commonly used in mathematical notation to denote the set of complex numbers that lie within a unit circle, specifically, those with positive real parts. The term "lunate" refers to its crescent shape, which differs from the typical uppercase Greek sigma (Σ) and lowercase sigma (σ). In digital text, the Greek Lunate Sigma Symbol serves as an essential tool for mathematicians, computer scientists, and engineers involved in complex number theory or electronic engineering. It has significant cultural and technical importance, particularly in the fields of mathematics, physics, and engineering, where it is utilized to indicate specific values or properties related to circular geometry or trigonometry. As an integral component of mathematical language, the Greek Lunate Sigma Symbol contributes to precision and clarity in digital communication across various scientific disciplines.
