Step 1: Determine the UTF-8 encoding bit layout
The character ¹ has the Unicode code point U+00B9. 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+00B9 to binary:
10111001. 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 10111001

Description
The Unicode character U+00B9, commonly known as the SUPERSCRIPT ONE (¹), plays a crucial role in digital text, particularly in mathematical expressions and scientific notations. This character is often used to denote superscripted numerals or letters, making it indispensable for proper representation of subscripted one, such as in atomic numbering or molecular formulae. In addition, U+00B9 is frequently employed within programming languages and markup languages to express power-related operations, exponents, and indices. Originally defined in the Latin-1 Supplement Unicode block (128-255), this character extends the basic Latin character set to accommodate additional symbols essential for proper formatting and presentation of written content. The versatility of the Latin-1 Supplement block is underscored by its characters' utility across numerous domains, from mathematics to computing, thereby ensuring clear communication and an aesthetically pleasing visual experience for readers.
