Step 1: Determine the UTF-8 encoding bit layout
The character ₀ has the Unicode code point U+2080. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800
to0xffff
.
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 thex
are 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+2080 to binary:
00100000 10000000
. 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 10000010 10000000

Description
The Unicode character U+2080, known as SUBSCRIPT ZERO, is a typographical element that plays a crucial role in mathematical and scientific digital text. Its primary function is to represent the numeral zero in subscript notation, which allows for the clear expression of terms or equations involving superscripts and subscripts. In this context, U+2080 is essential for maintaining the accuracy and readability of complex expressions that include powers, exponents, and indices. SUBSCRIPT ZERO is particularly significant in chemistry, where it is commonly used to denote the number of atoms in a chemical formula or the charge of an ion. This Unicode character ensures consistency and precision across various digital platforms and applications, contributing to effective communication in fields that rely on mathematical or scientific notation.
