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.
