Handling Character Encoding in URI on Tomcat
- by ZZ Coder
On the web site I am trying to help with, user can type in an URL in the browser, like following Chinese characters,
http://localhost:8080?a=??
On server, we get
GET /a=%E6%B5%8B%E8%AF%95 HTTP/1.1
As you can see, it's UTF-8 encoded, then URL encoded. We can handle this correctly by setting encoding to UTF-8 in Tomcat.
However, sometimes we get Latin1 encoding on certain browsers,
http://localhost:8080?a=ß
turns into
GET /a=%DF HTTP/1.1
Is there anyway to handle this correctly in Tomcat? Looks like the server has to do some intelligent guessing. We don't expect to handle the Latin1 correctly 100% but anything is better than what we are doing now by assuming everything is UTF-8.
The server is Tomcat 5.5. The supported browsers are IE 6+, Firefox 2+ and Safari on iPhone.
