UnicodeEncodeError: 'latin-1' codec can't encode character
当我试图向数据库中插入一个外部字符时,可能是什么导致了这个错误?
1 | >>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!
我在使用python mysqldb模块时遇到了同样的问题。由于MySQL允许您在文本字段中存储所需的任何二进制数据,而不管字符集如何,我在这里找到了我的解决方案:
在python mysqldb中使用utf8
编辑:引用上述URL以满足第一条评论中的请求…
"UnicodeEncodeError:'latin-1' codec can't encode character ..."
This is because MySQLdb normally tries to encode everythin to latin-1.
This can be fixed by executing the following commands right after
you've etablished the connection:
1 2 3 4 | db.set_character_set('utf8') dbc.execute('SET NAMES utf8;') dbc.execute('SET CHARACTER SET utf8;') dbc.execute('SET character_set_connection=utf8;') |
"db" is the result of
MySQLdb.connect() , and"dbc" is the result of
db.cursor() .
拉丁语1(ISO-8859-1)编码中不存在字符U+201C左双引号。
它出现在代码页1252(西欧)。这是一种基于ISO-8859-1的特定于Windows的编码,但它将额外的字符放在0x80-0x9f范围内。代码页1252经常与ISO-8859-1混淆,这是一种烦人的但现在却是标准的Web浏览器行为,如果您将页面作为ISO-8859-1提供服务,浏览器会将其视为CP1252。然而,它们实际上是两种不同的编码:
1 2 3 4 | >>> u'He said \u201CHello\u201D'.encode('iso-8859-1') UnicodeEncodeError >>> u'He said \u201CHello\u201D'.encode('cp1252') 'He said \x93Hello\x94' |
如果只将数据库用作字节存储,则可以使用CP1252对windows western代码页中的
您可以使用
最好的解决办法是

我希望你的数据库至少是UTF-8。然后您需要运行
您试图使用无法描述该代码点的编码
sqlacalchemy用户可以简单地将其字段指定为
例子:
sqlacalchemy只接受unicode对象并返回它们,处理编码本身。
文档
使用以下代码段将文本从拉丁语转换为英语
1 2 3 4 5 6 7 | import unicodedata def strip_accents(text): return"".join(char for char in unicodedata.normalize('NFKD', text) if unicodedata.category(char) != 'Mn') strip_accents('áéí?óúü') |
输出:
'aeinouu'

你的意思是使用UTF-8编码吗?
python:您需要添加#-*-编码:utf-8-*(去掉*周围的空格)到python文件的第一行。然后将以下内容添加到要编码的文本中:.encode("ascii","xmlcharrefreplace")。这将用它的ASCII等价物替换所有的Unicode字符。
