What common issue does the use of the German word 'März' present in PHP coding?

The common issue with using the German word 'März' in PHP coding is that it contains special characters (ä) which can cause encoding problems. To solve this issue, you can use the utf8_encode() function to convert the string to UTF-8 encoding, which will handle special characters properly.

$germanWord = 'März';
$encodedWord = utf8_encode($germanWord);

echo $encodedWord;
