My question was about the want for a construct that allows for accessing 
the n'th printable character in an UTF-8 string

Finding the 100000 th and then independently the 100005 th printable 
character needs quite a lot of CPU time, so it would be nice to have a 
kind of "enumerator" that (e.g.) in a smart way remembers a set of 
(Byte_Position / printable_Character_position) pairs helping to quickly 
find the n'th printable character.
