How to decode non-ASCII URLs

I am writing an HTTP server, and to test what messes it up, I entered ઔஇᆖ into a text field. The client request is

GET /add_text_data?message=%E0%AA%94%E0%AE%87%E1%86%96&category=log&color=black HTTP/1.1
Host: localhost
Connection: keep-alive
Cache-Control: max-age=0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.155 Safari/537.36
Accept-Encoding: gzip, deflate, sdch
Accept-Language: en-US,en;q=0.8

When I used URLDecodeer.decode("%E0%AA%94%E0%AE%87%E1%86%96", "UTF-8"), I got ???. How do I fix this?

It turns out that this is actually not an issue with URLDecoder, but with OutputStream. URLDecodeer.decode("%E0%AA%94%E0%AE%87%E1%86%96", "UTF-8").equals("ઔஇᆖ") is actually true. I just needed to set Eclipse to accept UTF-8 output. This question fixed it for me.

Looks like UTF-8 can't handle it.

You can test decoding here to see what kind of decoding you'd have to use.

Make sure you store the result in some kind of datatype that can accept unicode if you do.
