# Service: `i18n`

The `i18n` service handles internationalization and localization, allowing the application to support multiple languages.

## Methods

### `func Translate(messageID string) string`

### `func HandleIPCEvents(c *core.Core, msg core.Message) error`

`HandleIPCEvents` handles IPC messages related to language changes or translation requests.

### `func ServiceStartup(ctx context.Context, options application.ServiceOptions) error`

`ServiceStartup` initializes the i18n service, loading available languages and setting the default locale.
