Pasi Kallinen e14120b282 Add completely blank symbol set ...

The blank symbol set can be used with screen reader software
to prevent it from reading the map symbols.

Prevent a segfault when looking at the map and many symbols
share the same character. Don't list too many symbols when
looking at those, if many share the same character.
