title: Python - SQLite to CSV Writer Error - ASCII values not parsed
body: <p>Afternoon,</p>
  
  <p>I am having some trouble with a SQLite to CSV python script. I have searched high and I have searched low for an answer but none have worked for me, or I am having a problem with my syntax.</p>
  
  <p>I want to replace characters within the SQLite database which fall outside of the ASCII table (larger than 128). </p>
  
  <p>Here is the script I have been using:</p>
  
  <pre><code>#!/opt/local/bin/python
  import sqlite3
  import csv, codecs, cStringIO
  
  class UnicodeWriter:
      """
      A CSV writer which will write rows to CSV file "f", 
      which is encoded in the given encoding.
      """
  
      def __init__(self, f, dialect=csv.excel, encoding="utf-8", **kwds):
          # Redirect output to a queue
          self.queue = cStringIO.StringIO()
          self.writer = csv.writer(self.queue, dialect=dialect, **kwds)
          self.stream = f
          self.encoder = codecs.getincrementalencoder(encoding)()
  
      def writerow(self, row):
          self.writer.writerow([unicode(s).encode("utf-8") for s in row])
          # Fetch UTF-8 output from the queue ...
          data = self.queue.getvalue()
          data = data.decode("utf-8")
          # ... and reencode it into the target encoding
          data = self.encoder.encode(data)
          # write to the target stream
          self.stream.write(data)
          # empty queue
          self.queue.truncate(0)
  
      def writerows(self, rows):
          for row in rows:
              self.writerow(row)
  
  conn = sqlite3.connect('test.db')
  
  c = conn.cursor()
  
  # Select whichever rows you want in whatever order you like
  c.execute('select ROWID, Name, Type, PID from PID')
  
  writer = UnicodeWriter(open("ProductListing.csv", "wb"))
  
  # Make sure the list of column headers you pass in are in the same order as your SELECT
  writer.writerow(["ROWID", "Product Name", "Product Type", "PID", ])
  writer.writerows(c)
  </code></pre>
  
  <p>I have tried to add the 'replace' as indicated here but have got the same error. <a href="https://stackoverflow.com/questions/4650639/python-convert-unicode-to-ascii-without-errors-for-csv-file">Python: Convert Unicode to ASCII without errors for CSV file</a></p>
  
  <p>The error is the UnicodeDecodeError.</p>
  
  <pre><code>Traceback (most recent call last):
    File "SQLite2CSV1.py", line 53, in &lt;module&gt;
      writer.writerows(c)
    File "SQLite2CSV1.py", line 32, in writerows
      self.writerow(row)
    File "SQLite2CSV1.py", line 19, in writerow
      self.writer.writerow([unicode(s).encode("utf-8") for s in row])
  UnicodeDecodeError: 'ascii' codec can't decode byte 0xa0 in position 65: ordinal not in range(128)
  </code></pre>
  
  <p>Obviously I want the code to be robust enough that if it encounters characters outside of these bounds that it replaces it with a character such as '?' (\x3f).</p>
  
  <p>Is there a way to do this within the UnicodeWriter class? And a way I can make the code robust that it won't produce these errors.</p>
  
  <p>Your help is greatly appreciated.</p>
