Step 1: Determine the UTF-8 encoding bit layout
The character ≙ has the Unicode code point U+2259. 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+2259 to binary:
00100010 01011001. 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 10011001

Description
The Unicode character U+2259, also known as the "Estimates" symbol, is a mathematical symbol that represents an estimation of a value. It is commonly used in digital text to denote an estimated numerical quantity or approximation, typically within mathematical equations and expressions. This character is particularly useful in fields such as statistics, engineering, and economics where precise measurements may not be available or relevant. The Estimates symbol has no cultural or linguistic significance but serves as a valuable tool in the realm of digital text and technical contexts for approximating values.
