Illegal character - CTRL-CHAR

Thanks guys for you inputs. I am sharing solution might be helpful for others. The requirement was not to wipe out CONTROL CHAR, it should remain as it is in DB also and one WS sends it across n/w client should able to get the CONTROL CHAR. So I implemented the code as follow:

1. Encode strings using URLEncoder in Web-Service code.
2. At client Side decode it using URLDecoder

Sharing sample code and output bellow.
Sample code:

System.out.println("NewSfn");  
System.out.println(URLEncoder.encode("NewSfn", "UTF-8"));  
System.out.println(URLDecoder.decode("NewSfn", "UTF-8"));  

Output:

NewSfn  
New%0FSfn  
NewSfn 

So client will recieve CONTROL CHARs.

EDIT: Stack Exchange is not showing CONTROL CHAR above. NewSfn is like this New(CONTROL CHAR)Sfn.

I would do what OrangeDog suggest. But if you want to solve it in your code try:

replaceAll("[\\x00-\\x09\\x11\\x12\\x14-\\x1F\\x7F]", "")

\\x12 is the char.
