UnicodeEncodeError:&x27；ascii'；编解码器可以'；t编码字符'\xa8&x27；位置15：序号不在范围内（128）

python新手，我想我已经上了unicode课程。 我的堆栈：

• cx Oracle（5.1.3）
• 烧瓶（0.10.1）
• 炼金术（2.0）
• 烧瓶WTF（0.12）
• openpyxl（2.2.6）
• SQLAlchemy（1.0.8）

Python 3.4.3 virtualenv。 我正在开发一个小型的we应用程序，它允许用户上传excel工作簿，然后应用程序将这些行写入oracle数据库。我在使用Python2.7.10时开始出现此错误代码。我读到的大部分内容表明，这是由于我默认的python 2.X解释器编码。因此，我将代码移到了Python3.4.3虚拟环境中。这个错误仍在发生

在下面的代码中，我使用要插入行中的单元格类型压缩列类型。创建字典列表后，调用sqlalchemy进行插入。结果调用ExecuteMy

当遇到excel工作表中的版权、注册商标符号等特殊字符时，会发生此错误。下面的if条件是导致故障的原因。因为这些特殊字符是文本字符串的一部分，所以我希望python 3将is视为字符串，然后插入它

从我所有的阅读资料来看，python 3在默认情况下应该使用utf-8编码。我已经阅读了我使用的所有软件包，它们都使用utf-8编码。所以我不明白为什么它试图使用ascii编码这个字符串&因此出现了这个错误。我曾尝试对该值执行显式.encode（'utf-8'），但当excel单元格类型为“无”时，这会导致另一个问题。这意味着它是一个空单元。然后我得到了Nonetype没有编码属性错误

output_data = []
for row in allrows:
   row_dict = {}
        for fobject,cobject in zip(sortedtablecolumnsobject,row):
        ########################################################
        ##Validation & assignment
        ########################################################
            if fobject.type.name == "Text":
                row_dict[fobject.name] = str(cobject.value)
         output_data.append(row_dict)

这是表反射和插入发生的地方：

    m = db.MetaData()
    t = db.Table(tableinfo.table_name,m,autoload = True, autoload_with = db.engine)
    db.engine.execute(t.insert(),output_data)

我认为其中一个软件包未经我同意使用ascii编码：-）请帮助

编辑：

>import sys, locale
>sys.stdout.encoding
>'UTF-8'
>locale.getpreferredencoding(False)
>'UTF-8'

跟踪如下：

提供完整的回溯。什么是

locale.getpreferredencoding（False）

？什么是

sys.stdout.encoding

？Excel倾向于将版权符号作为实体而不是utf-8代码点来逃避，因此您可能需要添加一些代码来处理该问题。@J.F.Sebastian我添加了您要求的内容。正如你所看到的，一切都在utf-8中。因此，我不明白在插入oracle时如何/为什么使用ascii来尝试编码。这不是完全的回溯。请尝试调试器，以本地化错误，然后重试。有多个不同的字符编码可同时用于不同的目的，例如检查db连接编码。另外，您是否确定为用于运行db代码的相同环境提供了结果？
