Eliminate unseen and unique characters in Java or JavaScript

I am looking to eliminate the [LS], [LS] character that only shows up when pasted in Notepad++. This data was inserted in a way that it is hidden and can only be seen on a UTF-8 encoding editor. Additionally, I want to remove characters like phone; email; fax.

The codes I tried are as follows:

string.replaceAll("\\p{Cntrl}", "").replaceAll("[^\\p{Print}]", "");

However, this also removes Chinese characters which should not be removed. Is there a method to get rid of hidden and iconic characters without eliminating language characters?

Answer №1

When it comes to choosing between JavaScript and Java, your request is clear.

Your task involves eliminating hidden and special characters (Java / JavaScript)

In this case, opting for a JavaScript-based solution seems appropriate. One efficient method is using a simple regex pattern:

string.replace(/[\xa0\x00-\x09\x0b\x0c\x0e-\x1f\x7f]/g, '');

This regex will effectively remove any invisible characters while retaining letters and digits.
