Try this
String yourString= "This is a â¦sample ⦠Java class to show the issueâ¨\nHow to solve it?";
Pattern myPattern = Pattern.compile("[^a-zA-Z0-9]");
Matcher myMatcher = myPattern.matcher(yourString);
while(myMatcher.find())
{
String temp= myMatcher.group();
yourString=yourString.replaceAll("\\"+temp, " ");
}
System.out.println(yourString);
