Step 1: Determine the UTF-8 encoding bit layout
The character Δ has the Unicode code point U+0394. 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+0394 to binary:
00000011 10010100. 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+0394 is the Unicode code point for the Greek capital letter Delta (Δ). It is commonly used in mathematical formulas to represent a change in value or difference between two variables. In computer programming, it often symbolizes a function's output. Historically, Delta has played a significant role in various fields such as mathematics, physics, and engineering. Notably, it is central to the concept of "differential calculus" in mathematics. Its use extends beyond purely technical applications, appearing in Greek texts and translations across literature, history, and religion. As an essential character in both digital text and cultural contexts, the Greek capital letter Delta continues to serve as a versatile and indispensable symbol.
