>>> with open('ex.csv') as f:
...     print f.read()
...
"foo","bar"
"a",1.2
"b",2.3

>>>tbl = petl.fromcsv('ex.csv', quoting=csv.QUOTE_NONNUMERIC)
>>>print petl.look(tbl)

Traceback (most recent call last):
  File "pt.py", line 16, in <module>
    print petl.look(tbl)

    return [unicode(s, 'utf-8') for s in row]
TypeError: coercing to Unicode: need string or buffer, float found

Without the quoting petl converts numbers to strings, but I need to preserve the type of data values.
