The occurrence of Chinese garbled characters during Tomcat startup is usually caused by incorrect encoding settings in the system environment variables or configuration files. To solve the problem of Chinese garbled characters when Tomcat starts, you can try the following methods:

1. Set environment variables: Make sure the correct language and encoding are set in the system's environment variables. You can add the following variables to the system environment variables:

Variable name: LANG

Variable value: zh_CN.UTF-8 (UTF-8 encoding is suitable for most situations)

2. Check the Tomcat configuration file: Make sure the correct encoding is set in the Tomcat configuration file. Open the conf/server.xml file in the Tomcat installation directory, look for the URIEncoding attribute and make sure it is set to UTF-8 encoding:

<Connector port="8080" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" 
           URIEncoding="UTF-8" />

3. Check the JVM parameters: If you are using custom JVM parameters to start Tomcat, Make sure the correct encoding parameters are set in the startup script, for example:

-Dfile.encoding=UTF-8

4. Check the operating system language and regional settings: Make sure the operating system language and regional settings are Chinese or UTF-8 encoding.

5. Restart the Tomcat server: After making changes to the above settings, restart the Tomcat server to see if the Chinese garbled problem is solved.

Through the above methods, you should be able to solve the problem of Chinese garbled characters when Tomcat starts. If the problem persists, you may need to further check the related configurations of the system and Tomcat.
