I'd like to propose implementing linked messages for commonly reused text across our localization files. This approach would help us maintain consistency and reduce duplication in our translations.

For example, instead of repeating the same close translation across different components, we could define it once in a common section and reference it using Vue i18n's linking syntax:

import { defineLocale } from '../composables/defineLocale'

export default defineLocale({
  name: '...',
  code: '...',
  messages: {
    common: {
      actions: {
        close: '...', // Define the translation once
      },
    },
    toast: {
      close: '@:common.actions.close', // Reference the common translation
    },
  }
})

This pattern would make our localization more maintainable since we'd only need to update common phrases in one place. It would also help ensure consistent terminology throughout the interface.

What are your thoughts on adopting this approach?

I noticed that Hungarian, like many languages, has multiple ICU locale definitions - both a general language code (hu) and a region-specific variant (hu-HU). Each of these has slightly different formatting rules for things like dates, numbers, and currency.

For example, looking at the ICU data:

• hu: General Hungarian language settings
• hu-HU: Hungary-specific formatting rules

Should we consider supporting these regional variants in our localization system? While starting with the base language code (hu) covers most cases, we might miss some region-specific formatting nuances. Would implementing just the base language locale be sufficient for our needs, or should we plan to support regional variants as well?

Thanks for your PR! 😊

Regarding the common messages, I don't think its necessary as there are very few entries. It would make the logic too complex for such a small improvement in my opinion.

I'm not sure it's necessary to support all regional variants, if you look at https://ui3.nuxt.dev/getting-started/i18n/nuxt#supported-languages we can see that only variants for different countries have been implemented but I don't know much about other countries needs for locales 😬

Let's merge this and if it's needed someday, we can make another PR!
