Ok, if my understandig is wrong, how do YOU measure the length of a string? Do you always use count(), or is there an alternative?
The thing is that even count(), which gives you the number of *code points*, isn't necessarily what is desired - that is, the number of actual display characters. UTF is quite a complex beast and doing any operations on it _correctly_ generally requires a lot of care. If you need to do these kinds of operations, I would highly recommend to read up the basics of UTF and Unicode first (quick overview on Wikipedia: <http://en.wikipedia.org/wiki/Unicode#Mapping_and_encodings>).
arr.length is meant to be used in conjunction with array indexing and slicing (arr[...]) and its value is consistent for all string and array types for this purpose.
