Step 1: Determine the UTF-8 encoding bit layout
The character ≓ has the Unicode code point U+2253. 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+2253 to binary:
00100010 01010011. 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 10001001 10010011

Description
U+2253 (IMAGE OF OR APPROXIMATELY EQUAL TO) is a mathematical symbol in the Unicode standard, representing an approximate equality relation between two objects. It is commonly used in digital text for mathematics, specifically in fields such as science, engineering, and computer programming to convey that one object is approximately equal to another, rather than strictly equal. The character can be found under the category of "Mathematical Operators" in Unicode. While it may not have a specific cultural or linguistic context, its use is essential for clear communication of relationships between values in these disciplines. Its precise usage and interpretation help avoid confusion and ensure accuracy in calculations and equations.
