如何防止显示菱形问号符号，即使使用 mb_substr 和 utf-8 [英] How to prevent showing the diamond question mark symbol, even using mb_substr and utf-8

问题描述

我已经阅读了一些其他问题，尝试了答案，但最终没有结果.我得到的是例如这个

Μήπως θα έπρεπε να   ...

而且我无法删除那个奇怪的问号.我所做的是获取 RSS 提要的内容，该内容也被编码为<?xml version="1.0" encoding="UTF-8"?> 使用希腊语作为内容.

有什么办法可以解决这个问题吗?

<div><?php$entry->description = strip_tags($entry->description);echo mb_substr($entry->description, 0, 490);?>...

解决方案

这就是答案

mb_substr($entry->description, 0, 490, "UTF-8");

I have read some other questions, tried the answers but got no result at the end. What I get is for example this

Μήπως θα έπρεπε να � ...

and I can't remove that weird question mark. What I do is to get the content of an RSS feed that is encoded also to <?xml version="1.0" encoding="UTF-8"?> using Greek language for the content.

Is there any way to fix this?

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<div><?php
    $entry->description = strip_tags($entry->description);
    echo mb_substr($entry->description, 0, 490);
?> ...</div>

解决方案

This is the answer

mb_substr($entry->description, 0, 490, "UTF-8");
