Step 1: Determine the UTF-8 encoding bit layout
The character ₇ has the Unicode code point U+2087. 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+2087 to binary:
00100000 10000111
. 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 10000111

Description
The Unicode character U+2087 is known as SUBSCRIPT SEVEN, a typographical element primarily used for denoting mathematical notations or indexing within the realm of digital text. Its role is integral in expressions involving powers or superscripts where it represents the numeral '7' in subscript form. Although its usage might seem limited to mathematicians and scientists, SUBSCRIPT SEVEN plays a critical part in ensuring the accuracy and clarity of scientific documents, programming codes, and mathematical equations. In digital typography, it is often paired with other subscript or superscript characters, such as U+2084 (SUBSCRIPT FOUR) and U+2085 (SUBSCRIPT ONE), to provide a comprehensive notation system. Despite not having a direct linguistic or cultural context, SUBSCRIPT SEVEN is an essential character in various technical fields that rely on precise representation of mathematical expressions and indexing systems.
