Running emacs 25.2.2 on Kubuntu 17.10.
I have an Org mode file that is mostly in English but certain headlines contain text in Devanagari.
From Options -> Set Default Font, I have chosen Hack 13 size as my default font.
But Hack is not a good font to display Devanagari characters.
So, when I want to edit contents of those headlines, I narrow the buffer to that region using
C-x n s and using
C-x C-e, evaluate the following command which is part of the headline:
(face-remap-add-relative 'default :family "Lohit Devanagari")
But that still changes the font for the entire buffer when I widen using
C-x n w.
How do I achieve the behavior that I intend? Change the font back to the default when I widen?
