问题描述

我正在尝试删除 xml 输出中的奇怪字符.这是代码和输出:

似乎存在编码问题.我尝试添加，这是从 ical 到 xml 的转换:

解决方案

您的 HTML 文档不完整.您缺少整个 head 标签，它应该有一个内容类型元标签来指定内容和编码.现在浏览器必须猜测编码是什么，并且猜测错误.

一个正确的 HTML 文档有一个 head 标签和一个 title 标签，这是你添加元标签的地方:

<title>页面名称</title><meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>

I'm trying to remove weird characters in xml output. Here's the code and output:

It seems there are encoding issues. I have tried adding and this a convert from ical to xml:

解决方案

Your HTML document is incomplete. You are missing the entire head tag, which should have a content type meta tag that specifies the content and encoding. Right now the browser has to guess what the encoding is, and guesses wrong.

A correct HTML document has a head tag with a title tag, that's where you add the meta tag:

<head>
  <title>Page name</title>
  <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
</head>
