title: pd.read_csv is reading less rows than the expected
body: <p>I'm using pandas to read a csv file, beforehand I already know the file has 13,000 rows, and pandas reads just 9,500 without raising any errors... but here is the thing, when I use 'to_csv()' method, and open the file with excel, it has 13,000 rows, so I don't understand what's happening here...</p>
  
  <pre><code>raw_data = pd.read_csv(file
                     ,delimiter='|'
                     ,sep='|'
                     ,low_memory= False
                    )
  </code></pre>
