What are the potential pitfalls of converting character encodings between Excel and PHP using functions like iconv?

When converting character encodings between Excel and PHP using functions like iconv, potential pitfalls include loss of data or corruption of special characters if the encodings are not handled correctly. To avoid these issues, make sure to specify the correct input and output encodings when using iconv. 

// Specify the input and output encodings when using iconv to convert character encodings
$input_encoding = 'UTF-8'; // Input encoding from Excel
$output_encoding = 'ISO-8859-1'; // Output encoding for PHP

// Convert the string from Excel encoding to PHP encoding
$excel_string = 'example_string_from_excel';
$php_string = iconv($input_encoding, $output_encoding, $excel_string);

// Use the converted string in PHP
echo $php_string;
