For links with query string parameters that can contain special characters,
you need to URL encode the parameters with the java.net.URLEncoder.encode()
method. The HttpServletResponse.encodeURL() method that you have tried to
use doesn't encode special characters, it embeds a session ID for session
tracking (if needed) in the URL.
As a side note, you may want to use a numeric key instead of a string
provided by your users to avoid this problem (and possible other problems,
like key collisions). A user friendly name can be defined as a regular
column in the database and used in the user interface in place of the
internally maintained numeric key.
