Info manuals are displayed by an Info reader, and each Info reader has
its own solution for this problem (generally, substitution of ASCII
characters for undisplayable Unicode ones).

I was talking about reading NEWS in a general-purpose text-browsing
program, such as Less.  It is IMO not a good idea to prevent people
from doing that and requiring them to only read NEWS and ChangeLog
files in Emacs.

Can you show a real-life example, with a particular symbol, where
using a literal search is inconvenient?
