So, if you choose substitution: s/[^a-zA-Z0-9"' .?!-]//g

if transliteration (would be my choice): y/a-zA-Z0-9"' .?!-//cd

I'd still be inclined to escape the '-' in both cases: someone is all too likely to come along in a couple of years needing to add one more character to the allowed list, and the natural tendency would be to add it to the end.
