Typically I'd iterate by means outside the language (I've used simple iterators

signficantly.
Since the latter is needed for optimal result in nearly every solution.
While I of course do see that in many cases it does make sense to use a
full blown enumerator to to a loop that traverses an UTF-8 (or other
Unicode) string in terms of Unicode characters, with a loop variable
that represents the position of the Unicode character in the string (in
therms of what ? ), I feel that there are also many cases that only ask
for a simple loop that just offers a loop variable coded as a 32 bit UCS
Unicode character or as an UTF-8 string.
