Figuring out pinyin.I believe this is all functional.
I tried like 4 different methods of doing it. But I ended up with the easiest way, by adding another user button to add 1,2,3, or 4 to the string. And then it basically adds that tone to the previous letter.
A tiny speck more work for the user, but it saves the programmer an immense amount of work. And since both of those are me, it ends up saving me time.
Tomorrow I'm going to be testing it to ensure that everything works as it should, but so far it looks promising.
