I need to remove all special characters from string using Javascript but its unable to remove. Please find my code below.

```
function checkString(){
      var sourceString='a|"bc!@£de^&$f g';
      var outString = sourceString.replace(/[`~!@#$%^&*()|+\-=?;:'",<>\{\}\[\]\\\/]/gi, '');
      console.log('sourcestring',outString);
}

```

Here I could not get the expected output. I am getting this `abcÂ£def g` in console. Here I need to remove all special characters. Please help me to resolve this issue.
