Encoding for URL
Oct 3rd, 2006, 12:29am  
Just thought I would share this little bit with anyone who might run into a use for it.

I've got a UTF-8 string I'm going to put into a URL with characters that are not ASCII. Java's own URLEncoder class interprets Strings as ASCII and will mess up my UTF-8. This code runs through byte by byte to catch those UTF chars that are more than just 1 byte long!

Correctly converts things like "Sigur Rós" into "Sigur+R%C3%B3s"

Any suggestions for improvement would be appreciated!

String URLEncode(String string){
 String output = new String();
 try{
   byte[] input = string.getBytes("UTF-8");
   for(int i=0; i<input.length; i++){
     if(input[i]<0)
       output += '%' + hex(input[i]);
     else if(input[i]==32)
       output += '+';
     else
       output += char(input[i]);
   }
 }
 catch(UnsupportedEncodingException e){
   e.printStackTrace();
 }

 return output;
}
