写入CSV时发生UnicodeEncodeError

Question

当尝试使用下面的代码在@columns中写入数据时，我得到了以下错误： “UnicodeEncodeError:'ascii'编解码器无法对位置2中的字符u'\xc4'进行编码：序号不在范围（128）”

我试着运行编码/解码到ascii，但是。。。在

u'G\xe5ng'.encode('ascii')

。。。生成相同的错误消息。有什么办法解决这个问题吗？在

你必须在python doc中使用UnicodeWritergive

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([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)
