title: python csv unicode 'ascii' codec can't encode character u'\xf6' in position 1: ordinal not in range(128)
body: <p>I have copied this script from [python web site][1] This is another question but now problem with encoding:</p>
  
  <pre><code>import sqlite3

          for row in rows:
              self.writerow(row)
  </code></pre>
  
  <p>This time problem with encoding, when I ran this it gave me this error:</p>
  
  <pre><code>Traceback (most recent call last):
    File "makeCSV.py", line 87, in &lt;module&gt;
      uW.writerow(d)
    File "makeCSV.py", line 54, in writerow
      self.writer.writerow([s.encode("utf-8") for s in row])
  AttributeError: 'int' object has no attribute 'encode'
  </code></pre>
  
  <p>Then I converted all integers to string, but this time I got this error:</p>
  
  <pre><code>Traceback (most recent call last):
    File "makeCSV.py", line 87, in &lt;module&gt;
      uW.writerow(d)
    File "makeCSV.py", line 54, in writerow
      self.writer.writerow([str(s).encode("utf-8") for s in row])
  UnicodeEncodeError: 'ascii' codec can't encode character u'\xf6' in position 1: ordinal not in range(128)
  </code></pre>
  
  <p>I have implemented above to deal with unicode characters, but it gives me such error. What is the problem and how to fix it?</p>
