You need to use the android.net.Uri class:

String url = Uri.parse("http://www.example.com/index.php")
                .buildUpon()
                .appendQueryParameter("sutyp", sutyp)
                .build()
                .toString();

jsonobject = JSONfunctions.getJSONfromURL(url);

From the docs:

Encodes characters in the given string as '%'-escaped octets using the UTF-8 scheme. Leaves letters ("A-Z", "a-z"), numbers ("0-9"), and unreserved characters ("_-!.~'()*") intact. Encodes all other characters.

You could use URLEncoder.encode(string, "utf-8")

For example

String url = String.format("http://www.example.com/index.php?sutyp=%s", sutyp);
jsonobject = JSONfunctions.getJSONfromURL(URLEncoder.encode(url, "utf-8");

Here is a reference to the documentation
