## Detailed Description

### template <class T>
class Glib::ustring_Iterator< T >

The iterator type of Glib::ustring.

Note this is not a random access iterator but a bidirectional one, since all index operations need to iterate over the UTF-8 data. Use std::advance() to move to a certain position. However, all of the relational operators are available: `== != < > <= >=`

A writeable iterator isn't provided because: The number of bytes of the old UTF-8 character and the new one to write could be different. Therefore, any write operation would invalidate all other iterators pointing into the same string.
