JSON

When creating JSON data manually, how should I escape string fields? Should I use something like Apache Commons Lang's StringEscapeUtilities.escapeHtml, StringEscapeUtilities.escapeXml, or should I use java.net.URLEncoder?

The problem is that when I use SEU.escapeHtml, it doesn't escape quotes and when I wrap the whole string in a pair of 's, a malformed JSON will be generated.
