What are the recommended methods for translating cryptic characters into readable text in PHP, especially when dealing with data from external sources like Google queries?

When dealing with cryptic characters in PHP, especially when retrieving data from external sources like Google queries, it is recommended to use the `mb_detect_encoding` function to detect the encoding of the text and then convert it to a readable format using `mb_convert_encoding`. This ensures that the text is properly decoded and displayed correctly.

// Retrieve the text from an external source like a Google query
$originalText = "“Thèse chà racters âre crýpticâ€�";

// Detect the encoding of the text
$encoding = mb_detect_encoding($originalText);

// Convert the text to a readable format
$decodedText = mb_convert_encoding($originalText, 'UTF-8', $encoding);

echo $decodedText;
