Step 1: Determine the UTF-8 encoding bit layout
The character ⪙ has the Unicode code point U+2A99. 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+2A99 to binary:
00101010 10011001. 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 10101010 10011001

Description
The Unicode character U+2A99, known as the DOUBLE-LINE EQUAL TO OR LESS-THAN symbol, plays a significant role in digital text by serving as an operator in mathematical equations and comparisons within computer programming and scientific notation. It is often used to express relationships of inequality between two numbers or expressions, specifically when dealing with floating point values where the equality operator might not yield accurate results due to precision limitations. This character helps maintain accuracy in computations and calculations that require a higher degree of precision than what can be achieved using the standard equal-to sign (=). It is commonly utilized in programming languages such as C++, Java, and Python, as well as in mathematical software like Mathematica and MATLAB. Despite its technical nature, U+2A99 does not have any specific cultural, linguistic, or historical context.
