Step 1: Determine the UTF-8 encoding bit layout
The character ² has the Unicode code point U+00B2. 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+00B2 to binary:
10110010. 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 10110010

Description
The Unicode character U+00B2, also known as the SUPERSCRIPT TWO, is a crucial typographical symbol within digital text, particularly relevant in mathematical expressions and scientific notation. It serves to represent the numeral '2' in a superscript format, being displayed slightly above the baseline of surrounding text (e.g., 2x²). This characteristic makes it an essential tool for indicating powers or exponents in equations and formulas. While superscripts are utilized across various languages, the cultural, linguistic, or technical context of U+00B2 primarily revolves around numerical and mathematical applications rather than linguistics. The Latin-1 Supplement Unicode block, to which this character belongs (ranging from 128 to 255), includes a diverse array of characters essential for proper text formatting and typography in written content. U+00B2 is part of the Basic Multilingual Plane, which encompasses most common characters used across languages. As a versatile tool for precise communication, U+00B2 plays a vital role in ensuring clarity and aesthetics within digital text, with its usage predominantly prominent within STEM fields.
