BERLIN — Swiss Eurovision fans were getting ready Sunday to give a hero’s welcome to singer Nemo, who won the 68th Eurovision Song Contest with “The Code,” an operatic pop-rap ode to the singer’s journey toward embracing a nongender identity. The singer, who is Swiss but currently lives in Berlin, was to land in Zurich on Sunday night, national broadcaster SRF said. Switzerland’s contestant beat Croatian rocker Baby Lasagna to the title by winning the most points from a combination of national juries and viewers around the world. Nemo, 24, is the first nonbinary winner of the contest that has long been embraced as a safe haven by the LGBTQ community. Nemo is also the first Swiss winner since 1988, when Canadian chanteuse Celine Dion competed under the Swiss flag.
