Step 1: Determine the UTF-8 encoding bit layout
The character φ has the Unicode code point U+03C6. 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+03C6 to binary:
00000011 11000110. 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:
11001111 10000110

Description
The Unicode character U+03C6 is the Greek small letter Phi (Φ, φ), a crucial symbol in mathematics, science, and digital text. This alphabetical character holds significant cultural, linguistic, and technical importance as it serves as the sixth letter of the Greek alphabet. It has been widely adopted for its distinctive appearance and phonetic value, particularly in transliteration from Greek to other languages. In digital text, U+03C6 is primarily used in mathematics for denoting mathematical constants, such as the golden ratio or the base of the natural logarithm, as well as in the notation of various mathematical equations and functions. Its usage extends to computer programming, data encryption, and cryptography, where it often serves as a variable name or symbol due to its unique visual properties.
