When Stars defenseman Jani Hakanpää hopped on the ice at American Airlines Center on Dec. 21, he looked a bit different. For the first time in his career, Hakanpää had the correct Finnish spelling of his name on his NHL jersey with umlauts over the last two letters. But since playing his first game in the NHL, Hakanpää's name was spelled on all team gear without the umlauts. “That’s it.”Sumner said he called Hakanpää to make sure the team used the correct umlauts — Hakanpää uses circular umlauts, not square ones. Four players on the Stars’ AHL affiliate have a diacritic mark in their names: Swedish center Oskar Bäck, Czech winger Matěj Blümel, Swedish center Fredrik Karlström and Slovakian winger Marián Studenič.
