Backslash is added to Search text with apostrophe

Hi! Thank you for the support and great plugin.

We reported a bug about the search text not working when there’s an apostrophe in the string submitted. Here’s the link to the ticket: https://tinyurl.com/yd3ewsz3.
We tried the solution recommended but it wouldn’t work, but since it would be included in the October update, we settled with just waiting for it.

Now we also noticed that if the search text submitted has an apostrophe, a backslash character is added right before the apostrophe. For example when you type “nature’s path” on the search and click enter, the text input value becomes “nature\’s path”. Since there is an additional character in the text, the result becomes zero even if a “Nature’s Path” product exists. Please help us with this, thanks!
