9232	_languages.js should be removed from core (?)	Wiktor Walc		"The list of languages available in the editor core is specified in `core/lang.js`.

If I'm correct, the mentioned file (`_languages.js`) is used only by the `ui_languages.html` sample. The problem is that there is no such sample file in V4, besides if its only for demonstration purposes, it should not be somewhere in core.

How about using a different apporach when creating a similar ui_languages sample file?

 - gather the list of available languages from `CKEDITOR.lang.languages`
 - have a map ""country code -> country name"" defined directly in the ui_languages sample. It can even include names of countries for which we do not have a translation yet."	Bug	closed	Normal	CKEditor 4.0	UI : Language	4.0	fixed
