  - Len() should not be used when working with UTF-8 strings. Len() returns
    the length in bytes, not in characters, which is exactly the wrong thing
    for UTF-8 strings. Use String.Len() instead.

  - String.Upper() does not modify its argument, so the return value of it
    under that If is just thrown away.

And I have a question too: Since when can you use a string like an array?
Is that documented? At least it seems like it is a read-only array, which
complicates the solution to the second issue...
