What are some potential issues when saving Japanese text in PHP, especially when copying text from external sources like websites?

One potential issue when saving Japanese text in PHP is character encoding problems, especially when copying text from external sources like websites. To solve this, you can ensure that the text is properly encoded using functions like mb_convert_encoding() or iconv() before saving it to a database. 

// Example code snippet to properly encode Japanese text before saving
$japaneseText = "日本語のテキスト";

// Convert text to UTF-8 encoding
$japaneseText = mb_convert_encoding($japaneseText, 'UTF-8', 'auto');

// Save the properly encoded Japanese text to the database
// $pdo->prepare("INSERT INTO table_name (japanese_text) VALUES (:japaneseText)");
// $pdo->bindParam(':japaneseText', $japaneseText);
// $pdo->execute();
