Non ascii characters in URL param in camel

Question

I am using graph API of Facebook and I call it through camel framework. My query has non ASCII characters (e.g. küçük). I am getting the following exception:-

Cause: 
org.apache.commons.httpclient.URIException: Invalid query
at org.apache.commons.httpclient.URI.parseUriReference(URI.java:2049)
at org.apache.commons.httpclient.URI.<init>(URI.java:147)

Does camel support non ASCII characters in URI? If not, what other things can be done?

example URL: https://graph.facebook.com/?ids=http://www.example.com/küçük

Answer 1

"URL encoding replaces non ASCII characters with a "%" followed by hexadecimal digits." (more info here)

You could try this:

URL url = new URL(uri.toASCIIString()); 

or maybe

String xstr = URLEncoder.encode("维", "utf-8");
