I have a default installation of Tomcat 8.5.6. It seems like UTF-8 encoded requests are not being interpreted correctly, even though the docs say the default (if not in strict mode) should be UTF-8 everywhere these days. My java POST requests look like:
HttpPost post = new HttpPost(url);
post.setEntity(new UrlEncodedFormEntity(nameValuePairs, HTTP.UTF_8));
...
Testing, I see the tilde character ñ is not decoded correctly in my servlet handler:
public class MyServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, ...) {
String tildeTest = request.getParam("foo"); // no good.
}
}
if I explicitly set the encoding on the request before access, it decodes properly:
protected void doPost(HttpServletRequest request, ...) {
request.setCharacterEncoding("UTF-8");
String tildeTest = request.getParam("foo"); // works!
...
}
so I'm not sure if:
Tomcat 8.5.6 is not really using UTF-8 everywhere, and I need to set that manually in the config files somewhere.
My http request is missing some header which tells Tomcat which encoding to use - perhaps the http post is defaulting to some other encoding which Tomcat is just honoring.
Anyone know which one?
Thanks
