yes, transliteration of Snæfells (Sī nài fèi ěr) and matches https://zh.wikipedia.org/wiki/%E6%96%AF%E5%A5%88%E8%8F%B2%E5%B0%94%E7%81%AB%E5%B1%B1 which is linked as interwiki from https://is.wikipedia.org/wiki/is:Sn%C3%A6fellsj%C3%B6kull

Perhaps could be added as name:zh to http://www.openstreetmap.org/relation/5443646 which already has a name:ru transliteration
