Using htmlPurifier to filter input, can you escape & into &

Today, the operation students said that some garbled codes appeared in the background title, such as & and so on. I took a look at it because the third-party package htmlpurifier was used in the project, and the initial guess is that this package has made some escapes. After searching the Internet, I didn't find it. I only found someone discussing the issue in its official forum:
