Yeah, typing those UTF-8 chars are a lot harder than typing -- and ---
on several text editors ;-)

Here, I only type UTF-8 chars for accents (my US-layout keyboards are 
all set to US international, so typing those are easy).

Sphinx already does that by default[1], using smartquotes:

	https://docutils.sourceforge.io/docs/user/smartquotes.html

Those are the conversions that are done there:

      - Straight quotes (" and ') turned into "curly" quote characters;
      - dashes (-- and ---) turned into en- and em-dash entities;
      - three consecutive dots (... or . . .) turned into an ellipsis char.

So, we can simply use single/double commas, hyphens and dots for
curly commas and ellipses.

[1] There's a way to disable it at conf.py, but at the Kernel this is
    kept on its default: to automatically do such conversions. 

Thanks,
