How does the choice of character encoding impact the accuracy of byte calculations in PHP when working with strings?

When working with strings in PHP, the choice of character encoding can impact the accuracy of byte calculations because different encodings can represent characters using different numbers of bytes. To ensure accurate byte calculations, it's important to specify the correct character encoding when working with strings. 

// Specify the character encoding when working with strings to ensure accurate byte calculations
$string = "Hello, 你好";
$encoding = "UTF-8";
$byteCount = strlen(mb_convert_encoding($string, 'UTF-8', $encoding));
echo "Byte count: " . $byteCount;
