The might be just linefeeds ("\r") in the text.....

Did you try this too:
Expand|Select|Wrap|Line Numbers
  1. .replace(/\n|\r/,"#")
if this does not help do this to determince which characters are in the text:
Expand|Select|Wrap|Line Numbers
  1. v="Hallo\r\n"
  2. s=""
  3. for (i=0; i<v.length; i++) { s = s + v.charCodeAt(i); }
  4.  
The output of this example should be:
"72971081081111310"

and display back that data back in JSP page with JavaScript what will be your approach for this?

"JSP page with JavaScript "

JSP = JavaServer Pages

- Java is not equal to JavaScript
- I do not have (enough) knowledge about JSP
- I would display it so the it will look the same ;)
