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.
