Detailed Description

Simple string iterator to iterate over an UTF-8 string and peel off the code points in sequence. This iterator can always get the 'next' code point, which is useful for function which require sequential code point pairs, such as kerning. The iterator terminates when the current character is nil, invalid, or at the 'end' pointer.
