[PATCH 52/53] docs: virt: kvm: avoid using UTF-8 chars

From: Mauro Carvalho Chehab
Date: Mon May 10 2021 - 06:40:42 EST


While UTF-8 characters can be used at the Linux documentation,
the best is to use them only when ASCII doesn't offer a good replacement.
So, replace the occurences of the following UTF-8 characters:

- U+00a0 (' '): NO-BREAK SPACE
- U+2013 ('–'): EN DASH
- U+2014 ('—'): EM DASH
