Tomcat garbled characters may be caused by a variety of reasons. To solve this problem, you need to analyze the specific situation and take corresponding measures. The following are some possible solutions:

1. Set the correct character encoding: Ensure that the character encoding used by the Tomcat server and client is consistent. Common character encodings include UTF-8 and ISO-8859-1. You can set the character encoding in the Tomcat configuration file, for example, set the URIEncoding attribute of the Connector element in the server.xml file to UTF-8.

2. Modify Tomcat's default encoding: Tomcat's default encoding may not be UTF-8. You can modify the default encoding by modifying Tomcat's configuration file. The Connector element can be found in the server.xml file in Tomcat's conf directory and set protocol="HTTP/1.1" and URIEncoding="UTF-8".

3. Set the correct locale: Ensure that the locale of the Tomcat server is set correctly. You can set the locale in the Tomcat configuration file, for example, set java.util.logging.ConsoleHandler.encoding to UTF-8 in the logging.properties file in the conf directory.

4. Check the character encoding requested by the client: If the client uses the wrong character encoding when sending the request, it may also cause garbled characters. You can specify the correct character encoding in the client request, for example, set Content-Type to application/x-www-form-urlencoded;charset=UTF-8 in the HTTP request header.

5. Modify the default locale of Tomcat: If the default locale of the Tomcat server is not Chinese, it may cause garbled characters. You can modify Tomcat's default locale to Chinese, for example, set LANG=zh_CN in the catalina.bat file in the conf directory.

6. Check the character encoding of the database connection: If the Tomcat server uses the wrong character encoding when connecting to the database, it may also cause garbled characters. You can check whether the character encoding of the database connection is correct, for example, specify the character encoding as UTF-8 in the database connection string.

7. Check the character encoding of the JSP page: If the JSP page uses the wrong character encoding, it may also cause garbled code problems. You can add <%@ page contentType="text/html;charset=UTF-8" %> to the header of the JSP page to specify the correct character encoding.

8. Modify the Tomcat server's log file encoding: If the Tomcat server's log file uses the wrong character encoding, it may also cause garbled characters. You can modify the Tomcat server's log file encoding to UTF-8, for example, set java.util.logging.ConsoleHandler.encoding to UTF-8 in the logging.properties file in the conf directory.

9. Modify the default locale of Tomcat server to Chinese: If the default locale of Tomcat server is not Chinese, it may cause garbled code problems. You can modify the default language environment of the Tomcat server to Chinese, for example, set LANG=zh_CN in the catalina.bat file in the conf directory.

10. Check the Java version installed on the Tomcat server: If the Java version installed on the Tomcat server is incompatible with the Tomcat version, garbled characters may occur. You can check whether the Java version installed on the Tomcat server is compatible with the Tomcat version. If it is not compatible, you need to upgrade or downgrade the Java version.

In short, solving the Tomcat garbled problem requires comprehensive consideration of multiple factors, including servers, clients, databases, operating systems, software, and browsers. When solving the problem of garbled characters, you need to investigate the possible causes one by one and take corresponding measures to solve it. At the same time, it is also necessary to strengthen the character encoding management of the entire system to ensure consistent character encoding throughout the system.
