Step 1: Determine the UTF-8 encoding bit layout
The character Ψ has the Unicode code point U+03A8. 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+03A8 to binary:
00000011 10101000
. 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+03A8, the Greek Capital Letter Psi (ΓΚΑΠΣ), holds a significant position in the realm of Unicode and typography. This character is often utilized in digital text, particularly within the context of ancient Greek scripts and mathematical symbols. The Psi, or Ψ (psi) is derived from the Semitic script Ph (as found in Phoenician and Hebrew) and signifies the 'ps' sound. It stands as the 23rd letter of the Greek alphabet, often employed in transliterations of ancient texts and transcriptions of historical documents. The Psi symbol also holds prominence in mathematical notation, where it is used to represent the lowercase psi, a fundamental element in various mathematical concepts such as the psi function, psychoanalysis, and statistics (Pearson product-moment correlation coefficient). Overall, U+03A8 serves as an indispensable character in digital communication and documentation, showcasing both linguistic and cultural significance while fulfilling technical requirements.
