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

Description
The Unicode character U+00AF, known as the MACRON (macron-u-00af), serves a crucial role in typography and digital text representation. This diacritical mark is commonly employed to indicate long vowel sounds in several languages, including French, Portuguese, and Icelandic. In digital text, it can be combined with vowels like A (Á), E (É), I (Í), O (Ó), and U (Ú) to represent the corresponding long vowel sounds or diphthongs. The MACRON is vital in preserving linguistic accuracy and facilitating readability in multilingual contexts, where understanding the correct pronunciation of words is crucial. In technical contexts, it is used for denoting certain types of measurements, such as time in hours (e.g., 5h) or temperature in degrees Celsius (e.g., 23°C). This Unicode character belongs to the Latin-1 Supplement block (latin-1-supplement), which includes characters ranging from 128 to 255 serving various text formatting and typography purposes, such as symbols like pilcrows (◊) and en dashes (–). The MACRON is part of the Basic Multilingual Plane (basic-multilingual-plane), which contains most common characters used in modern written languages. Its usage contributes significantly to accurate digital text representation and effective communication across various cultures, languages, and disciplines.
