Step 1: Determine the UTF-8 encoding bit layout
The character Ā has the Unicode code point U+0100. 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+0100 to binary:
00000001 00000000. 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 Unicode character U+0100, also known as LATIN CAPITAL LETTER A WITH MACRON, is a significant typographical symbol in digital text representation. This character is used to denote the Latin capital letter 'A', but with an added macron diacritic mark, which is represented by a horizontal line over the letter. In linguistic and cultural contexts, this character serves as a crucial tool for representing distinct phonological features that may not be present in other languages using the Latin alphabet. The macron, typically signifies a long vowel sound or an elongated syllable. For example, in Irish Gaelic, "Á" represents /ɑː/ while "A" stands for /a/. The usage of U+0100 is predominantly technical, playing an essential role in digital typography, particularly in word processing, typesetting, and text encoding systems that require accurate representation of specific linguistic features or phonetic nuances. In the realm of linguistics and cultural studies, it facilitates precise transcription and translation, thereby fostering effective communication across different languages and dialects. This character belongs to the Latin Extended-A Unicode block, a crucial component of the Unicode system that expands the capabilities of the Latin alphabet for various languages. The macron is one of several diacritical marks in this block, designed to cater to the unique phonetic and orthographic needs of various languages using Latin-based scripts. In summary, the LATIN CAPITAL LETTER A WITH MACRON (U+0100) is an indispensable character in digital text, offering a precise typographical tool for representing elongated vowel sounds and distinct linguistic features across various languages using the Latin alphabet.
