#1 (fix included) unprintable characters in clue preclude displ

[Dr. Robert J. Meier]

When the cursor moves to a clue with a nonprintable
character, the old clue continues to be shown, and the
clue with unprintable character is never shown.

The following patch corrects this problem by removing
the unprintable characters.
