Step 1: Determine the UTF-8 encoding bit layout
The character ɸ has the Unicode code point U+0278. In UTF-8, it is encoded using 2 bytes because its codepoint is in the range of
0x0080
to0x07ff
.
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 thex
are 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+0278 to binary:
00000010 01111000
. 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+0278, known as the Latin Small Letter Phi (ϕ), is a letter within the Unicode Standard that represents the lowercase form of the Greek letter Phi (Φ). In digital text, it is commonly used to represent the symbol "φ" in typography and mathematical equations. While not part of the standard 26-letter English alphabet, this character has significant cultural, linguistic, and technical contexts. In ancient Greece, Phi was considered sacred and symbolized beauty and harmony. It is often used as a shorthand for the concept of "Golden Ratio," which plays a crucial role in aesthetics, mathematics, and nature. The Golden Ratio is an irrational number, approximately equal to 1.61803398875, and has been found in various aspects of art, architecture, and design throughout history. In modern usage, the Latin Small Letter Phi (ϕ) is commonly employed in fields such as mathematics, physics, engineering, and computer science to denote a specific function or concept. For example, it is often used to represent the phi function in number theory and to signify magnetic flux in electromagnetism equations. As a result, the character U+0278 has become a significant tool for researchers, mathematicians, and typographers seeking precision and clarity in their digital text communication across various disciplines.
