Step 1: Determine the UTF-8 encoding bit layout
The character δ has the Unicode code point U+03B4. 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+03B4 to binary:
00000011 10110100. 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+03B4 is the Unicode character code for "GREEK SMALL LETTER DELTA". It is used to represent the Greek letter Delta (∆) in digital text. The character plays a significant role in various fields, particularly in mathematics and science where it is often used as a symbol for change or difference, such as in the concept of the derivative in calculus. In linguistics and computer programming, it can be employed to denote the fourth letter of the Greek alphabet. Although primarily associated with its use in the Greek language, Delta has also been adopted into English and other languages due to its widespread adoption as a mathematical symbol. The character is part of the Unicode Standard, which ensures consistency and interoperability across different systems and platforms when using characters from diverse writing systems worldwide.
