Maybe I don't understand the o(1) correctly. Do you think it should be 
necessary to access each character in the string with in each iteration 
in this way.

What I meant was:

A pointer to the first UTF8-Code of the next Unicode character is the 
internal invisible loop variable.

A string containing the multi-Byte code of the current Unicode character 
is the visible loop variable.

Constructing the string and the pointer at the start of each loop is 
straight forward (regarding the UTF-8 definition), fast, o(1) and does 
not need a table.
