If we are already using vue-i18n v8 and operating with the localize service, we will need to convert your resource format to vue-i18n v9 because it is incompatible.

- special characters

### Suggested solution

We suggestion a new command `transform` to convert the resource from vue-i18n v8 to v9.

By providing this command, it is also possible to convert in a CI environment such as github actions.
