URLEncoder.encode(String url) is deprecated.  Java wants you to use URLEncoder.encode(String url, String enc).  But what do you put for the encoding parameter?  I always forget which is the whole point of this post. 🙂

URLEncoder.encode(url, "UTF-8");

Also on Windows if you want you can do:

URLEncoder.encode(url, "Cp1252");

For further reading please see default encoding of a jvm.
