Detailed Description

uni_iter is a non-mutating iterator that walks through unicode code points in the UTF8 encoded string.

The normal ++(), ++(int), ->(), and *() operators are all supported for read only access and some return an unsigned holding the unicode character appropriate for the respective operator.
