Step 1: Determine the UTF-8 encoding bit layout
The character ⁻ has the Unicode code point U+207B. 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+207B to binary:
00100000 01111011. 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 10111011

Description
The Unicode character U+207B, also known as SUPERSCRIPT MINUS, is a specialized typographical symbol used predominantly in mathematical and scientific digital text. This character serves an essential role in various fields such as physics, chemistry, engineering, and mathematics by denoting the subtraction operation when it appears in superscript position. Unlike its counterpart U+002D HYHEN-MINUS, which is used to separate words or denote a minus sign in normal text size, SUPERSCRIPT MINUS has a specific application in expressions where the subtraction needs to be clearly indicated while maintaining consistency with other superscripts. The character can be found within several programming languages and word processing software that support Unicode encoding. While its usage is limited to specific contexts, the SUPERSCRIPT MINUS is an indispensable tool for clarity and accuracy in various technical disciplines where mathematical notation or chemical formulas are essential.
