(Copy of)URL Contains Special characters
You can encode like this,

public class URLUTF8Encoder
{   
 final static String[] hex = {
 "%00", "%01", "%02", "%03", "%04", "%05", "%06", "%07",
 "%08", "%09", "%0a", "%0b", "%0c", "%0d", "%0e", "%0f",
 "%10", "%11", "%12", "%13", "%14", "%15", "%16", "%17",
 "%18", "%19", "%1a", "%1b", "%1c", "%1d", "%1e", "%1f",
 "%20", "%21", "%22", "%23", "%24", "%25", "%26", "%27",
 "%28", "%29", "%2a", "%2b", "%2c", "%2d", "%2e", "%2f",
 "%30", "%31", "%32", "%33", "%34", "%35", "%36", "%37",
 "%38", "%39", "%3a", "%3b", "%3c", "%3d", "%3e", "%3f",
 "%40", "%41", "%42", "%43", "%44", "%45", "%46", "%47",
 "%48", "%49", "%4a", "%4b", "%4c", "%4d", "%4e", "%4f",
 "%50", "%51", "%52", "%53", "%54", "%55", "%56", "%57",
 "%58", "%59", "%5a", "%5b", "%5c", "%5d", "%5e", "%5f",
 "%60", "%61", "%62", "%63", "%64", "%65", "%66", "%67",

      int len = s.length();
      for (int i = 0; i < len; i++) {
      int ch = s.charAt(i);

       sbuf.append((char)ch);

       sbuf.append(hex[0x80 | (ch & 0x3F)]);
    }
   }
    return sbuf.toString();
       }
     }

Use the URLEncoder class.

Example:

String argument = "Nårska täcken";
String encoded = URLEncoder.encode(argument, "utf-8");
// encoded contains "N%C3%A5rska+t%C3%A4cken"

Just be careful you don't encode a whole URL query string in one go, since that ends up encoding the ? and = as well.

String query = "?myQuery=Nårska+Täcken";
String encoded = URLEncoder.encode(query "utf-8");
// XXX BAD! encoded contains "%3FmyQuery%3DN%C3%A5rska%2Bt%C3%A4cken"
