How can PHP developers troubleshoot and resolve discrepancies in character conversion, such as the incorrect display of special characters like the euro symbol?

PHP developers can troubleshoot and resolve discrepancies in character conversion by ensuring that the correct character encoding is used throughout the application. If special characters like the euro symbol are not displaying correctly, developers can use functions like utf8_encode() or utf8_decode() to properly encode or decode the characters. 

// Example code snippet to fix incorrect display of euro symbol
$euroSymbol = "\xe2\x82\xac"; // Euro symbol in UTF-8 encoding
$correctEuroSymbol = utf8_encode($euroSymbol);
echo $correctEuroSymbol; // Output: €
