Step 1: Determine the UTF-8 encoding bit layout
The character ⊖ has the Unicode code point U+2296. 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+2296 to binary:
00100010 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 10001010 10010110

Description
The Unicode character U+2296, known as the Circled Minus, serves a unique purpose in digital text representation. This typographical element is often utilized within mathematical equations or scientific notation to represent the standard minus sign (-) enclosed by a circle. Its primary function is to differentiate between the traditional minus sign and other similar symbols in specific contexts, enhancing readability and preventing misinterpretation. The Circled Minus has found particular relevance in fields such as physics, engineering, and computer science due to its ability to clarify mathematical operations or depict variables within equations. Despite its limited usage in everyday text, the Circled Minus plays a crucial role in specialized domains where precision is critical.
