WordPress在帖子内容中错误地显示了HTML实体和十六进制实体

Question

我将以下代码保存为运行TwentyNineteen主题的未经修改的Wordpress安装中的帖子内容。它包含HTML实体和十六进制实体的组合。

<span>Explore the professions of some of the groundbreaking women in 
science, technology, engineering and mathematics (STEM) with the LEGO&Acirc;&reg; Ideas Women of NASA set.

Role-play space exploration from planning to moon landing, beginning with the iconic scene from Massachusetts Institute of Technology in 1969 of Hamilton with software that she and her team programmed. Build the posable Hubble Space Telescope and launch a LEGO version of the Space Shuttle Challenger with 3 removable rocket stages.

当内容显示在网站的前端时，实体无法正确显示。看起来是某种形式的UTF-8编码问题？

我查看了this UTF-8 debug tool website，发现错误的字符与我希望在表的左侧找到的字符匹配。

我尝试过：

• 将utf8_decode（）应用于post_content
• 将htmlentities（）应用于post_content
• 从post_content删除wptexturize过滤器

这些都没有为我工作。我认为问题更复杂，可能与原始文本的字符编码有关吗？它来自基于Windows的系统的XML响应。这与Windows字符编码有关吗？

更新

对此问题的评论表明，此问题是在WordPress掌握之前发生的。我正在通过PHP中的cURL从基于Windows的API请求XML中的内容，然后使用simplexml_load_string对其进行解析。如果我将XML响应直接转储到文件，则编码正确。见下文。
