Django HTML 模板中的特殊字符

Question

我正在尝试在 Django HTML 模板中写一些带有特殊字符的东西，例如“é”或“ê”，但它不起作用。并且 Django 返回此错误消息：

UnicodeDecodeError at /
'utf8' codec can't decode byte 0x97 in position 248: invalid start byte

这是整个回溯： 环境：

呈现模板的视图：

def home(request):
    if request.user.is_authenticated():
        browser_stats = [['Chrome', 52.9], ['Firefox', 27.7], ['Opera', 1.6],
                     ['Internet Explorer', 12.6], ['Safari', 4]]
        return HttpResponseRedirect('/profile/')
    else:
        return render(request, 'home.html')

模板的url：

url(r'^$', 'survey.views.home', name='home'),

Answer 1

三件事：

• 请放

# -*- coding: utf-8 -*-

在 .py 文件的开头。

• 该 .py 文件必须是不带 BOM 文件的 UTF-8（编码 - 从 Notepad++ 转换为不带 BOM 的 UTF-8）

• 此外，包含 Unicode 字符的文本字符串应以 u 开头。所以你应该写text=u'unicode here'这样的东西。

如果您仍然看到相同的错误，请提供完整的堆栈跟踪。此外，<meta charset="utf-8"> 与客户端相关，与 django 异常无关。
