Step 1: Determine the UTF-8 encoding bit layout
The character ¨ has the Unicode code point U+00A8. 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+00A8 to binary:
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:
11000010 10101000

Description
The Unicode character U+00A8, commonly known as the DIAERESIS, plays a crucial role in digital text by modifying the pronunciation of certain letters. In linguistic contexts, it is frequently used in French and other Romance languages to indicate the nasalization of vowels. Specifically, when placed above the letter 'a', it signifies a pronounced sound as in the word 'naïve'. Though less common, this symbol can also appear over the letters 'e' or 'o', such as in the words 'fœtus' and 'café'. From a technical perspective, the DIAERESIS is an essential part of Unicode, a computing industry standard for encoding text that allows digital texts to be displayed uniformly across various platforms. Its inclusion in Unicode ensures accurate representation and consistent rendering of characters and symbols, thus facilitating clear and effective communication in multilingual contexts. The DIAERESIS is found in the Latin-1 Supplement Unicode block (128 to 255), a versatile collection of characters that serve various text formatting and typography purposes. This range of characters includes symbols like pilcrows, en dashes, and others, which are essential for proper formatting and presentation of written content. The Latin-1 Supplement block was designed to extend the basic Latin character set in order to accommodate these additional symbols, thereby enhancing the readability and overall appearance of text documents. Its characters can be utilized across a wide range of applications, from professional documents to creative writing, ensuring clear communication and an aesthetically pleasing visual experience for readers.
