Strings are UTF-8 encoded, and thus characters can differ in the amount of length they take up in the string (string length is measured in bytes, not human readable characters). Try inputting one special character which takes up more than 1 byte, then another character of any type. The program will immediately panic. That, in addition to the fact that you're using these iterators to remove singular characters, shows that Vec<char> would be a much better choice.

Take a look at https://github.com/lj3954/linutil/tree/pr_176, I've added 2 commits that would probably be helpful.
