Then using the same solution as not just for Info, Emacs will automatically
substitute ASCII characters for undisplayable Unicode ones in all
other places like NEWS and ChangeLogs.

Not only ‘M-s .’, more so ‘M-s _’ where neither ‘M-s _ C-M-y’
nor ‘M-s _ C-M-w’ work when used at the beginning of the symbol.

It's a good habit to use symbol search to search symbols because
it reduces the likelihood of errors, so using it should be
encouraged in NEWS and ChangeLogs.
