A small scenario to describe an issue:
I have a CONTENT TYPE with 5 fields.
- Go to admin/config/regional/content-language.
- Enable translation for only 2 fields.
- Then created a node in the german language(original language) and also added translation for the FRENCH language.
Now my site doesn't require the German language(original language). So if I remove the german language completely from the site then I lose data for the non-translatable fields which were initially added in the german language.
Above issue occur for all entities. Is there any way I can remove language without losing any data?
