Jshint unescaped regex characters

I am trying to clear Javascript code using jshint. In a third-party script that is used, jshint complains about unescaped javascript in this line:

var cleanString = deaccentedString.replace(/([|()[{.+*?^$\\])/g,"\\$1");

I would also like to understand what this regular expression does, but I don't see it. Can someone tell me what it is for and how to write it on a cleared path?

Thanks for any tips.

It matches any of the following characters: |()[{.+*?^$\and replaces it with its escaped instance (backslash plus this character).

regex [ , , :

var cleanString = deaccentedString.replace(/[|()\[{.+*?^$\\]/g,"\\$0");

( .)

"" . , "[" , . :

var cleanString = deaccentedString.replace(/([|()\[{.+*?^$\\])/g,"\\$1");
