Support custom locales

We support languanges in contries that are not the “default” like english in germany, en-DE, english in sweden and japan, en-SE & en-JP etc.

This is current stopping from using Dato since we would have redesign a lot of internal system to work around this “issue”.

Please add support for custom locales.
