Step 1: Determine the UTF-8 encoding bit layout
The character ≅ has the Unicode code point U+2245. 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+2245 to binary:
00100010 01000101. 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 10000101

Description
The Unicode character U+2245, known as "Approximately Equal To," holds a significant position in mathematical notation and digital text. This symbol is primarily employed to denote an approximation or near equality between two values or expressions, particularly in contexts where precise equality may not be applicable. Its role is essential in various fields including mathematics, engineering, physics, computer science, and economics. The usage of this character helps avoid ambiguity in calculations or comparisons, aiding readers in understanding the level of accuracy they should expect when interpreting results. It is also crucial to note that U+2245 has no direct linguistic value and is primarily used for its technical function.
