Searching words that include apostrophes don't always work in admin search

[lamisalhassanieh]

Hello,

If I enter a word that includes an apostrophe like this (’) into the posts search field, I get no results. While this (') works successfully.

This can be an issue if user copied texts from somewhere else like web pages or word documents and tried to search.

Possibly the same issue reported long ago: #13178

In testing, I found that by copying and pasting the word person’s in from a texturized page leads to a search query that looks like wp-admin/edit.php?s=person’s and it yields different results than if a straight quote is used in a search query that gets URL encoded like /wp-admin/edit.php?s=person%27s
