Step 1: Determine the UTF-8 encoding bit layout
The character ï has the Unicode code point U+00EF. 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+00EF to binary:
11101111. 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:
11000011 10101111

Description
The Unicode character U+00EF, also known as the Latin Small Letter I with Diaeresis (í), plays a significant role in digital text representation. In various languages such as Spanish, French, Portuguese, Swedish, and others, this diacritical mark helps correctly depict the specific pronunciation of the letter "i," shifting its sound closer to "ee." Culturally and linguistically, the character U+00EF enhances accurate communication and comprehension across multiple cultures that employ these languages. Technically speaking, it is crucial for digital platforms like websites, software applications, and electronic documents, where adherence to Unicode standards ensures proper representation of written language. The Latin Small Letter I with Diaeresis resides in the Latin-1 Supplement Unicode block (U+0080 to U+00FF). This range of characters extends the basic Latin character set, accommodating additional symbols essential for proper formatting and presentation of written content. The Latin-1 Supplement block was designed with versatility in mind, catering to text formatting purposes ranging from pilcrows (◊) and en dashes (–) to numerous others. Its characters are widely utilized across various applications, spanning professional documents to creative writing, ensuring clear communication while providing an aesthetically pleasing visual experience for readers.
