Remove all symbols, html and special chars from string
Question
How can I remove all elements from a string apart from raw text and a single space? However, certain symbols are not getting removed, - , –, ’
Currently I use:
let descriptionString = description.replace(/(<([^>]+)>)/gi, "").replace(/[^a-zA-Z 0-9]+/g,"");
description is a field from wordpress which can contain anything, html, symbols, encoded chars etc.
Example content is:
Surgical Sim 8211 Kate O8217Connor Sim Lab I need to remove 8217 - its only removed the hash at the moment.
I need to display the result in a react-native View . I don't want to use a WebView to render html .
Any ideas?

Check the below function. It removes all the special charactors, html and symbols.
function filterString(html)
{
var tmp = document.createElement("DIV");
tmp.innerHTML = html;
tmp = tmp.textContent || tmp.innerText || "";
tmp =tmp.replace(/([,"'0-9\-.~!@#$%^&*()_+=–’`{}\[\]\|\\:;"<>\/?])+/g, '').replace(/^(-)+|(-)+$/g,'');
return tmp;
}
console.log(filterString("<html>asdasjhd<body>%dasd test - , ' –, ’ ytest jsdnja @!@#@&^$@$ "));
Also you can test it for your string
console.log(filterString("Surgical Sim 8211 Kate O8217Connor Sim Lab"));
