Step 1: Determine the UTF-8 encoding bit layout
The character has the Unicode code point U+0081. 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+0081 to binary:
10000001. 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 10000001

Description
U+0081, code 129, char , is a Latin Small Letter A with Grave Accent (ʻa) character in the Unicode Standard. This diacritical mark is utilized in digital text representation, particularly within languages using the Latin script for typographical purposes. The grave accent (´) alters the pronunciation and meaning of the preceding vowel "a" in linguistic contexts, notably in French language usage. Outside of linguistics, U+0081 may also serve as a non-breaking space within certain software applications. It belongs to the Latin-1 Supplement Unicode block (ranging from 128 to 255), which extends the basic Latin character set to accommodate additional symbols necessary for proper text formatting and presentation in various contexts, from professional documents to creative writing. This versatile range of characters enhances readability and visual appeal across multiple applications, thus fostering clear communication and an aesthetically pleasing experience for readers. The Latin-1 Supplement block is a part of the Basic Multilingual Plane (0-65535), which contains most common characters used in everyday digital text.
