Step 1: Determine the UTF-8 encoding bit layout
The character Ä has the Unicode code point U+00C4. 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+00C4 to binary:
11000100. 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+00C4, also known as "LATIN CAPITAL LETTER A WITH DIAERESIS", plays a significant role in digital text, particularly in languages such as German, Swedish, and Norwegian. In these languages, it represents a distinct phoneme or sound that doesn't exist in English. The diaeresis (two small dots above the 'A') indicates a long vowel sound that differs from the standard "A" sound. This character is essential for maintaining accuracy in translations and preserving the original pronunciation of words from these languages. From a technical standpoint, U+00C4 is part of the ISO 8859-1 charset, one of the first character encodings used for Western European languages before Unicode became the standard. In digital typography, proper usage of this character contributes to clear and accurate communication across different languages that use the Latin script. It belongs to the Latin-1 Supplement Unicode block (U+0080 to U+00FF), a versatile collection of 256 characters essential for proper formatting and presentation of written content in digital text. This range includes symbols like pilcrows, en dashes, and others that are crucial for various text formatting and typography purposes.
