How Koreans Pronounce Duchamp's Name

I was looking over last year's first grade middle school art test, and low and behold, what do I see but a picture of Duchamp's "Bicycle Wheel." But in the question I saw how his name was written, and it was as follows: 뒤샹. This would effectively be pronounced as Dwee-Shyang. I thought of my dearest boyfriend and his French studies and figured this would make his skin crawl, hence leading to my writing about it. The end.
