Step 1: Determine the UTF-8 encoding bit layout
The character ⨢ has the Unicode code point U+2A22. 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+2A22 to binary:
00101010 00100010. 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 10101000 10100010

Description
The Unicode character U+2A22, known as the Plus Sign with Small Circle Above (⊗), plays a significant role in various fields including mathematics, science, and engineering. It is commonly used to represent multiplication or an operation that combines two numbers or quantities. This character stands out due to its distinctive appearance, featuring a standard plus sign (+) with a small circle above it. The small circle accentuates the multiplication aspect of the symbol, differentiating it from other plus signs that might be used in addition or other arithmetic operations. Despite being less commonly used than the standard plus sign or times symbol (x), the U+2A22 character is beneficial in contexts where clarity and precision are essential, such as mathematical equations, programming languages, and scientific notations.
