答案 0 :(得分：1)
以下是我使用value
>>> type(value)
<type 'str'>
>>> v = value.decode('utf-8')
>>> type(v)
<type 'unicode'>
如果您想了解value是否已编码或已解码，则可以从错误消息中看到，如果您尝试UnicodeDecodeError已编码的字符串，则会引发encode 。
那么尝试然后捕获异常怎么样：
try:
value = value.encode('utf-8')
except UnicodeDecodeError:
print('It is already a UTF-8 encoded string')
else:
print('It may have been a UTF-8 encoded string')
