I have the following string:

Backpacks‎

Which if you copy and paste into the website http://asciivalue.com/ to examine each ascii char inside that string, you can see that after the text 'Backpacks' there is the ascii value: ‎ , this value messes up when I try to write the string to a csv file, as it will get outputted as Backpacksâ€Ž

I have tried using .replace functions like subcategoryStr.replace(/[^\x00-\x7F]/g, ""); and replace(/[^\x20-\x7E]/g, ''); to remove any of these invisible nonstandard ascii but no luck, how can I remove this invisible character from a string in javascript?

Hmmm, that's a left-to-right unicode mark – SuperStormer Feb 24 '21 at 00:48

`String.prototype.replace` returns a new string. Strings in JS are immutable – ASDFGerte Feb 24 '21 at 00:48

tried using `subcategoryStr.replace(/[\u0000-\u001F\u007F-\u009F]/g, "");` but no change, still has the left to right unicode mark @SuperStormer – Martin Feb 24 '21 at 00:52

More directly: use `subcategoryStr = subcategoryStr.replace(/[^\x00-\x7F]/g, "");` – ASDFGerte Feb 24 '21 at 00:53
that works thanks @ASDFGerte – Martin Feb 24 '21 at 00:56
