Set Game Language Code

Configures the platform to synchronize the language used in the game.

1. When the user changes the game's language in the settings, this API is called to set the platform language, and the corresponding value is saved in the game data.

2. If there is a saved game language setting, the platform can be started with the saved game language by calling this API before the Start API during the next game launch.

The following language codes are supported:

• device: Uses the device's language setting value (default). This is used when you want to revert to the device's setting after setting a specific language.

• en: English

• ko: Korean

• ja: Japanese

• zh_hant: Traditional Chinese

• zh_hans: Simplified Chinese
