What is the best practice for decoding quoted printable and converting to UTF-8 in PHP?

When decoding quoted printable text and converting it to UTF-8 in PHP, it is best practice to use the `quoted_printable_decode()` function to decode the quoted printable text, and then use the `mb_convert_encoding()` function to convert the decoded text to UTF-8. 

// Input quoted printable text
$input = '=E6=97=A5=E6=9C=AC=E8=AA=9E';

// Decode quoted printable text
$decoded_text = quoted_printable_decode($input);

// Convert decoded text to UTF-8
$utf8_text = mb_convert_encoding($decoded_text, 'UTF-8', 'ISO-2022-JP');

echo $utf8_text;
