"" However, the regex =a-c= actually matches the string =a-c=, contrary to what the example says. It should be [!^a-c] instead of =a-c=. Also, in both paragraphs above (""character ranges"" and ""single characters"") regexes like =[abc]= and =[a-c]= are used in place of [abc] and [a-c], respectively.
