哪位帮忙看一下这个问题困扰好几天了再搞不定就会出问题了望各位多帮忙

还是字符编码的问题。

你先用type(variale)看一下变量的类型，是unicode还是str.
最好帖些代码上来

栈回退显示编码问题

0xa4 不是有效的utf-8字符，确定你的文档是按照utf-8编码或者兼容编码保存，否则就要转换。
话说你在做繁体开发？

何以见得是繁体我是想把linux上的一个程序移植到windows上我出错的这个view肯定是utf8的我拿Ultra Edit 转换过不过其他的被调用的模块就不敢保证了我下午全转了试试

ccporxy 发表于 2011-06-14 13:48

你转下这个脚本文件应该就ok了
resolveTask/newSample.htm
不过不排除其他的也有问题
最好的方法就是 settings.FILE_CHARSET 设置文本保存的编码

jizhanlong 发表于 2011-06-14 17:54

多谢各位帮忙问题终于解决了问题就出在那个htm上重新转码一下就行了
请教一下ccporxy 你说的那个最好的方法不太明白麻烦解说一下谢了

django配置说明：
https://docs.djangoproject.com/en/1.0/ref/unicode/#ref-unicode

Don’t be fooled into thinking that if your DEFAULT_CHARSET setting is set to something
other than 'utf-8' you can use that other encoding in your bytestrings!
DEFAULT_CHARSET only applies to the strings generated as the result of template rendering (and e-mail).
Django will always assume UTF-8 encoding for internal bytestrings. The reason for this is that the DEFAULT_CHARSET
setting is not actually under your control (if you are the application developer). It’s under the control of the person
installing and using your application – and if that person chooses a different setting, your code must still continue to
work. Ergo, it cannot rely on that setting.

这里看来使用utf-8还是最好的选择。
