What are the limitations of using mb_detect_encoding() in PHP for encoding detection, especially with Latin-1 characters?

When using mb_detect_encoding() in PHP for encoding detection, especially with Latin-1 characters, there can be limitations due to the algorithm used for detection. This can result in inaccurate or incorrect encoding detection for Latin-1 characters. To improve accuracy, you can manually check for Latin-1 encoding using mb_check_encoding() or iconv_strlen() functions. 

// Check for Latin-1 encoding manually
function detectLatin1Encoding($string) {
    if(mb_check_encoding($string, 'ISO-8859-1')) {
        return 'ISO-8859-1';
    } else {
        return mb_detect_encoding($string);
    }
}

// Example usage
$string = "This is a Latin-1 encoded string: café";
$encoding = detectLatin1Encoding($string);
echo "Detected encoding: " . $encoding;
