What is the method to determine if a tomcat setup supports UTF-8?

edit

There are a few ways to determine if a Tomcat setup supports UTF-8:

1. Check the server.xml file: Open the server.xml file located in the conf folder of your Tomcat installation directory. Look for the Connector element and check if the URIEncoding attribute is set to UTF-8. If it is, then your Tomcat setup supports UTF-8.

2. Check the web.xml file: Open the web.xml file located in the WEB-INF folder of your web application. Look for the encoding filter and check if the character encoding is set to UTF-8. If it is, then your web application is using UTF-8.

3. Send a request with UTF-8 characters: Send a request to one of your web application's pages containing UTF-8 characters. If the page displays the characters correctly, then your Tomcat setup supports UTF-8. If not, you may need to configure your setup to support UTF-8 by following the steps above.
