What are the potential pitfalls of assuming that CSV data does not contain delimiters like commas or semicolons?

Assuming that CSV data does not contain delimiters like commas or semicolons can lead to incorrect parsing of the data, resulting in data corruption or processing errors. To solve this issue, it is important to properly handle delimiters by using a CSV parsing library or function that can correctly identify and separate the data fields. 

// Example of using PHP's built-in fgetcsv function to properly parse CSV data with delimiters
$filename = 'data.csv';
$delimiter = ',';
$header = NULL;
$data = [];

if (($handle = fopen($filename, 'r')) !== FALSE) {
    while (($row = fgetcsv($handle, 1000, $delimiter)) !== FALSE) {
        if (!$header) {
            $header = $row;
        } else {
            $data[] = array_combine($header, $row);
        }
    }
    fclose($handle);
}

print_r($data);
