what you think about this idea :

java code

public class Main {

    public static void main(String[] args) {
        String str="gasd@!dfas%";
        String newStr="";
          for (int i=0;i<str.length();i++)
          {
              //Ascci range for a-z A-Z
              if (str.charAt(i)>64&&str.charAt(i)<121)
              {
                    newStr+=str.charAt(i);
              }
          }

         System.out.println("String before filter "+str);
        System.out.println("String after filter "+newStr);

    }

}

That depends on what you define as special characters, but try replaceAll(...):
String result = yourString.replaceAll("[-+.^:,]","");
