Step 1: Determine the UTF-8 encoding bit layout
The character π has the Unicode code point U+03C0. 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+03C0 to binary:
00000011 11000000. 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 character U+03C0 (GREEK SMALL LETTER PI) plays a significant role in digital text, particularly within the realm of computer science and mathematics. This Unicode character is used to represent the lowercase Greek letter "π," commonly referred to as Pi. Pi holds immense importance in both fields due to its mathematical properties and its fundamental role in various equations and theories, such as geometry and physics. Specifically, it serves as a constant approximately equal to 3.14159, representing the ratio of a circle's circumference to its diameter. Consequently, its usage extends beyond digital text into real-world applications where geometry is integral, like architecture and engineering. In addition to its mathematical applications, U+03C0 (GREEK SMALL LETTER PI) also appears in Greek language texts and historical documents, further emphasizing the character's cultural and linguistic significance. Overall, this Unicode character remains a vital tool for both technical and humanities-based contexts.
