如何使用 HTML Purifier 使行为正常？
我在 PHP 项目中使用 HTML Purifier ，但无法使其与用户输入正常工作。
我让用户使用 WYSIWYG 编辑器 (TinyMCE) 输入 HTML，但是每当用户输入 HTML实体 （不间断空格）它作为这个奇怪的外来字符（Â）保存到数据库中。
然而，问题是，当我使用所见即所得编辑器编辑保存的条目时，它会正确显示为 。 它在显示时也能正常工作，只是在源代码中它显示为真实的空格，而不是不间断的空格字符。
此外，在 MySQL 数据库中，它显示为奇怪的外来字符。
我阅读了有关 Unicode 和 HTML Purifier 的文档，并将我的数据库和网页编码更改为是 UTF-8，但我仍然遇到不间断空格字符未被破坏的问题。 其他 HTML 实体，例如 < 和 >，保存为 < 和 >< /code>，但为什么不是 ？
I am using HTML Purifier in my PHP project and am having trouble getting it to work properly with user input.
I am having users enter in HTML using a WYSIWYG editor (TinyMCE), but whenever a user enters in the HTML entity (non-breaking space) it gets saved into the database as this weird foreign character (Â).
However, the thing is, when I edit the saved entry using the WYSIWYG editor it gets displayed properly as . It also functions properly when displayed, only that in the source code it appears as a real space, but not the non-breaking space character.
Also, in the MySQL database it displays as the weird foreign character.
I read the doc about Unicode and HTML Purifier and changed my database and web page encoding to be UTF-8, but I am still having problems with the non-breaking space character not being mangled. The other HTML entities, such as < and >, get saved as < and >, but why not ?

不间断空格不会作为一个奇怪的外来字符保存在数据库中，而是保存为两个字符。 Unicode 不间断空格字符在 UTF-8 中编码为
0xC2 0xA0，在 ISO-8859-1 中看起来像“ ” （即一个奇怪的外来字符后跟一个不间断的空格）。您可能忘记在数据库连接上执行
SET NAMES 'utf8'，这会导致 PHP 将其数据作为 ISO-8859-1（默认值）发送到 MySQL。查看“UTF-8 all the way through...”即可了解使用 PHP 和 MySQL 时如何正确设置 UTF-8。
The non-breaking space isn't being saved in your database as one weird foreign character, it's being saved as two characters. The Unicode non-breaking space character is encoded in UTF-8 as
0xC2 0xA0, which in ISO-8859-1 looks like "Â " (i.e. a weird foreign character followed by a non-breaking space).You're probably forgetting to do
SET NAMES 'utf8'on your database connection, which causes PHP to send its data to MySQL as ISO-8859-1 (the default).Have a look at "UTF-8 all the way through…" to see how to properly set up UTF-8 when using PHP and MySQL.
