Step 1: Determine the UTF-8 encoding bit layout
The character ➖ has the Unicode code point U+2796. 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+2796 to binary:
00100111 10010110
. 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 10011110 10010110

Description
The Unicode character U+2796, also known as the Heavy Minus Sign, is a typographical symbol used primarily in digital text for mathematical operations, specifically subtraction. This character serves to differentiate itself from the regular hyphen (-) and en dash (–), providing clarity when representing subtraction or negative values in equations or mathematical expressions. While it may not be as widely recognized as other mathematical symbols, the Heavy Minus Sign holds significance for its specific role in denoting subtraction operations within certain contexts. The use of this symbol can be seen in digital text, such as in computer programming languages and scientific documents, to ensure accurate interpretation by software and readers alike.
