Make sure that your application server is configured to serve the file name characters that you use in your Web applications. If you serve files that include non-English characters in their file names, configure your application server to handle URL requests using Unicode (UTF-8) characters.
For example, if you are using the Oracle WebLogic application server, add the following element to your weblogic.xml
file.
<charset-params> <input-charset> <resource-path>/*</resource-path> <java-charset-name>UTF-8</java-charset-name> </input-charset> </charset-params>
See the documentation for your Java application server software for more information about serving files with non-English characters in their file names.
