Uncommon (Unorthodox?!) Pinyin: What are these? I find this sort of uncommon, unorthodox, whatever you wanna call it, pinyin very fascinating. These are the ones that I know of already - that, apparently, are still considered to be Mandarin. What I'm wondering is, are there others? What other wild, bizarre pinyin(s) exist in Mandarin and what characters go along with them?
