我有这个字符串已经使用电子邮件模块从Quoted-printable解码为ISO-8859-1.这给了我像"\ xC4pple"这样的字符串,它们对应于"Äpple"(Apple中的瑞典语).但是,我无法将这些字符串转换为UTF-8.

>>> apple = "\xC4pple"
>>> apple
'\xc4pple'
>>> apple.encode("UTF-8")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc4 in position 0: ordinal not in     range(128)

我该怎么办？

当我尝试将外来字符插入数据库时​​,可能导致此错误的原因是什么？

>>UnicodeEncodeError: 'latin-1' codec can't encode character u'\u201c' in position 0: ordinal not in range(256)

我该如何解决？

谢谢!

我正处于一个我调用api的场景,并根据api的结果我为api中的每条记录调用数据库.我的api调用返回字符串,当我通过api为数据库调用返回的项时,对于某些元素,我得到以下错误.

Traceback (most recent call last):
  File "TopLevelCategories.py", line 267, in <module>
    cursor.execute(categoryQuery, {'title': startCategory});
  File "/opt/ts/python/2.7/lib/python2.7/site-packages/MySQLdb/cursors.py", line 158, in execute
    query = query % db.literal(args)
  File "/opt/ts/python/2.7/lib/python2.7/site-packages/MySQLdb/connections.py", line 265, in literal
    return self.escape(o, self.encoders)
  File "/opt/ts/python/2.7/lib/python2.7/site-packages/MySQLdb/connections.py", line 203, in unicode_literal
    return db.literal(u.encode(unicode_literal.charset))
UnicodeEncodeError: 'latin-1' codec can't encode character u'\u2013' in position 3: ordinal not in range(256)

上面错误引用的代码段是:

         ...    
         for startCategory in value[0]:
            categoryResults = []
            try:
                categoryRow = ""
                baseCategoryTree[startCategory] = []
                #print categoryQuery % {'title': startCategory}; 
                cursor.execute(categoryQuery, {'title': …
