CK Editor 4 does not support Hindi, typeset or copy

I am trying to implement a Hindi font for data entry and copying in a PHP site using a CK editor. This works great when the text is copied from any web resource or existing Hindi content on the Internet. However, it does not work when data is copied from MS Word or when we try to enter content in the editor itself.

Already links to Add Hindi Font in CK Editor .

Also can't find config.font_names as suggested in other posts.

After the link is implemented, the font is added to the list, but after the selection, when we try to enter or copy from a word, the specified data is ambiguous. Any help is appreciated
