Misled

Enigma

They were certain nobody could read it. They were wrong. Answers are entered across and down, each beginning at its numbered square. A few squares belong to one entry only. At ten squares the across answer and the down answer want different letters. Write both into the square, in alphabetical order. Twenty characters are printed below the grid. It's up to you to figure out what they are trying to tell you. The six squares beneath them are for your answer.
