The Mayor of Diyarbakir, Turkey is being sued and could go to jail for six months for sending out greeting cards reading "Happy New Year." At issue is the letter "W"...really.
The Turkish alphabet doesn't have the letter W...but the Kurdish alphabet does. State agencies and other groups have been ordered to use the Turkish alphabet, so the mayor technically violated the "w law" by having the word "New" on his greeting card.
As a warning, keep in mind X and Q are also not allowed in Turkey...which make scrabble even more boring.
