and escaped accordingly.

Also, the fallbackLng: dev default is not usually helpful.

 See the [i18next documentation](https://www.i18next.com/overview/api#init) for setting it up. `i18next-vue` does not need a lot of setup on top of that.

+We do recommend to set the `interpolation: {escapeValue: false}` option ([i18next docs](https://www.i18next.com/translation-function/interpolation#all-interpolation-options)), because - except in `v-html` - Vue will already properly escape values intended as plain text.
