Step 1: Determine the UTF-8 encoding bit layout
The character Π has the Unicode code point U+03A0. 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+03A0 to binary:
00000011 10100000. 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+03A0 represents the Greek capital letter "Pi" (Π). In digital text, it is primarily used to transcribe and convey information in the Greek alphabet, as well as in mathematics and scientific contexts due to its phonetic resemblance to the Latin 'P'. The letter Pi holds significant cultural, linguistic, and technical importance. In ancient Greece, it was a part of the early Phoenician script, and later the Euboean script, both of which greatly influenced the development of the modern Greek alphabet. Its numerical value in the Greek alphabet is 16, signifying its position as the sixteenth letter. Additionally, Pi (π) has become synonymous with the mathematical constant representing the ratio of a circle's circumference to its diameter, which is approximately equal to 3.14159. As a result, this character is widely employed in various mathematical fields and scientific disciplines.
