Java EE (Java Enterprise Edition) General Discussion

I have a html form which occassionally has text input containing curly quotes. This is posted to my servlet and written as text to an xml file. However, an error occurs, due to the curly quotes and the xml file never gets written.
I've tried unsuccessfully to write some javascript to replace the curly quotes with straight quotes. The problem here is that the servlet cannot handle curly quotes when it downloads the javascript.
Can anyone help with this please?
