Jeff, I tried java 1.4 and it seemed to work, only partly. When using java.net.URLEncoder.encode(KanjiURL, "UTF-8"); it will encode the "://" from http://somehost.com and all subsequent "/" characters into a form that is unacceptable to java.net.URL. By encoding the non-ascii filename only and then appending it to http://somehost.com/ and then passing that into java.net.URL it seems to work. After getting this to work I searched for UTF-8 on google and found this page: ftp://ftp.isi.edu/in-notes/rfc2279.txt There is a java class for encoding unicode strings. I had to change it slightly to ignore "/" and ":" and then it worked perfectly. And it works with the 1.3 compiler and plugin. I'm copying the files below this but they include japanese characters so I'm unsure how they'll appear in your mail client. If anyone wants then emailed please contact me: these will create two applets. both applets will have 3 buttons that download a non ascii filename image. the first button will download using a url that Apaches provides when it lists the file as an index. the second button tries a non ascii URL. the third button tries a UTF-8 encoded the first and third button will have an image , the middle one will not. ************** Extract from Apache Log ************************ 127.0.0.1 - - [15/Jan/2003:17:08:42 +0900] "GET /icons/%e6%bc%a2%e5%ad%97.gif HTTP/1.1" 200 242 127.0.0.1 - - [15/Jan/2003:17:08:42 +0900] "GET /icons/漢字.gif HTTP/1.1" 404 283 127.0.0.1 - - [15/Jan/2003:17:13:23 +0900] "GET /icons/%e6%bc%a2%e5%ad%97.gif HTTP/1.1" 200 242 127.0.0.1 - - [15/Jan/2003:17:13:23 +0900] "GET /icons/漢字.gif HTTP/1.1" 404 283 10.51.132.144 - - [15/Jan/2003:17:14:30 +0900] "GET /icons/%e6%bc%a2%e5%ad%97.gif HTTP/1.1" 304 0 10.51.132.144 - - [15/Jan/2003:17:14:30 +0900] "GET /icons/漢字.gif HTTP/1.1" 404 283 10.51.132.144 - - [15/Jan/2003:17:14:30 +0900] "GET /icons/漢字.gif HTTP/1.1" 404 283 10.51.132.144 - - [15/Jan/2003:17:14:30 +0900] "GET /icons/%E6%BC%A2%E5%AD%97.gif HTTP/1.1" 304 0 ****************************************************** /* ************* Java 1.4 ***************/ import javax.swing.*;
