Regular expressions match characters instead of bytes. For instance,
-"." matches a character instead of a byte. (However, the C<\O> pattern
-is provided to force a match a single byte ("octet", hence C<\O>).)
+"." matches a character instead of a byte. (However, the C<\C> pattern
+is provided to force a match a single byte ("C<char>" in C, hence
+C<\C>).)
