> Using Python 2, converting Pandas with 'str' data to Arrow results in Arrow data of binary type, even if the user supplies type information.  conversion of 'unicode' type works to create Arrow data of string types.  For example
> {code}
> In [25]: pa.Array.from_pandas(pd.Series(['a'])).type
> Out[25]: DataType(binary)
> In [26]: pa.Array.from_pandas(pd.Series(['a']), type=pa.string()).type
> Out[26]: DataType(binary)
> In [27]: pa.Array.from_pandas(pd.Series([u'a'])).type
> Out[27]: DataType(string)
> {code}
