Step 1: Determine the UTF-8 encoding bit layout
The character ⁴ has the Unicode code point U+2074. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800to0xffff.
Therefore we know that the UTF-8 encoding will be done over 16 bits within the final 24 bits and that it will have the format:1110xxxx 10xxxxxx 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+2074 to binary:
00100000 01110100. 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:
11100010 10000001 10110100

Description
The Unicode character U+2074 represents the superscript numeral '4'. It is typically used in mathematical expressions, scientific notations, and chemical formulas to denote an exponent or a power of four. This character can be found in various typesetting software and programming languages that support Unicode encoding. Although not widely used, it plays an essential role in maintaining consistency and clarity in scientific documents and research publications where powers and exponents are frequently employed. The usage of U+2074 in digital text ensures precise communication of mathematical concepts and prevents misunderstandings resulting from the misinterpretation of traditional numerals as exponents or subscripts.
