I don't think that's right: iterating over the the string should
presumably generate a iteration of valid sub-strings, each of length
one.  It would not generate a sequence of integers.

  [x for x in "abc"] != [ord(x) for x in "abc"]

'o\u0308'[1] should generate an ArrayBounds exception, since you're
indexing into a string of length 1.
