我正在开发使用python的Flask (可能与这个问题无关) web应用程序。我得到了这个错误：UnicodeDecodeError: 'utf8' codec can't decode byte 0xe8 in position 5: invalid continuation byte。我将# -*- coding: utf-8 -*-放在文件的顶部，但仍然得到相同的结果。这是代码的一部分：

s+="Searching results for: \"%s \"<br><br>".encode("utf-8") % (pattern)

    for i in orderedList[0:10]:
        a=a+1
        res=(SC.dictionaryMemory.get(i))

        try:
            resString= ', '.join(res)
        except:
            print("Chyba!")

        with open('somefile.txt', 'a') as the_file:
            the_file.write(resString)

        s+="<b>%s: </b>%s,<br>".decode("utf-8") % (i, resString.decode("utf-8"))

    return (s.decode("utf-8") if (len(orderedList)>0) else "Nebyli nalezeny zadne vyrazy.".encode("utf-8")))

这是我在html页面上得到的回溯：

File "C:\Python27\lib\site-packages\flask\app.py", line 1836, in __call__
return self.wsgi_app(environ, start_response)
File "C:\Python27\lib\site-packages\flask\app.py", line 1820, in wsgi_app
response = self.make_response(self.handle_exception(e))
File "C:\Python27\lib\site-packages\flask\app.py", line 1403, in handle_exception
reraise(exc_type, exc_value, tb)
File "C:\Python27\lib\site-packages\flask\app.py", line 1817, in wsgi_app
response = self.full_dispatch_request()
File "C:\Python27\lib\site-packages\flask\app.py", line 1477, in full_dispatch_request
rv = self.handle_user_exception(e)
File "C:\Python27\lib\site-packages\flask\app.py", line 1381, in handle_user_exception
reraise(exc_type, exc_value, tb)
File "C:\Python27\lib\site-packages\flask\app.py", line 1475, in full_dispatch_request
rv = self.dispatch_request()
File "C:\Python27\lib\site-packages\flask\app.py", line 1461, in dispatch_request
return self.view_functions[rule.endpoint](**req.view_args)
File "D:\workspace\AproximateSearchPython2\WebApp.py", line 74, in search
s+="<b>%s: </b>%s,<br>".decode("utf-8") % (i, resString.decode("utf-8"))
File "C:\Python27\lib\encodings\utf_8.py", line 16, in decode
return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xe8 in position 5: invalid continuation byte

在我看来问题出在resString的内容上。在somefile.txt中是这样的：

společné, obecný, veřejný, společný, prostý, obyčejný, obvyklý, obecný, společný, běľný

你能给我一些建议吗？

编辑:我把decode改成了encode，但还是出现了同样的问题。
