You can define the language and language code using Language Definition.
Expand Library Server Parameters in the navigation pane.
Right-click Language Definitions and select New to open the New Language Definition
page.
Enter the Language in the Language field.
Select the Language Code from the Language Code drop-down list.
Click OK to save the language definition. Click the Apply button to save the language
definition and keep the page/window open to create another language definition.
The new language must also be added to the languages.xml configuration file in the

the cache is reloaded.
