It seems that all ways to iterate over the characters in a UTF8 string
have quadratic running time. See the attached test. I would expect that
for keyed access and 'substr' but iterator access and 'split' should
have better performance. I had a look at the string iterator PMC code
and it doesn't use the iterators that the underlying string API provides.
I can offer to write a patch to fix this if noone else is working on this.
Good idea! Patches welcome!
