Turkish alphabet problems

[bilgenotlar]

Some characters specific to the Turkish alphabet cannot be used in the puzzle table. However, they can be used as clues. However, when you want to print as a pdf, the Turkish characters in the clue descriptions cannot be used again.

The pdf issue is related to #198 - our current PDF renderer just doesn't seem to support rendering much beyond ascii characters.

In terms of supporting add'l characters in the grid, it's related to #446 - any chance you can enumerate which add'l chars are necessary to fully support the Turkish alphabet?
