Step 1: Determine the UTF-8 encoding bit layout
The character ⁰ has the Unicode code point U+2070. 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+2070 to binary:
00100000 01110000
. 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 10110000
SUPERSCRIPT ZERO·U+2070

Description
The Unicode character U+2070, also known as the Superscript Zero, is a typographical symbol that serves a specific purpose in digital text formatting. It is used to denote a number that should be displayed as a superscripted zero. This character plays a vital role in mathematical expressions and equations where a zero needs to be displayed in a raised position. The Superscript Zero is often employed in subscripts, powers, or exponents, such as in algebraic expressions or scientific notation. However, it's worth noting that the usage of this character might be less common due to the fact that many digital text editors and word processors automatically render zeroes as superscript when used in such contexts, thus eliminating the need for U+2070 explicitly. Despite its relatively niche application, the Superscript Zero holds significance in ensuring precise representation of mathematical expressions and maintaining typographical accuracy.
