Two Ü make so much trouble

[szsdk]

I think I find the reason for these two issues.

1. Unknow script output #1 (comment)
2. Apple Script not working #5 (comment)

Because there are two Ü. One is U+00DC, the devil. If you directly copy from the website, you probably will end up with this. The right one but actually is two chars: U+0055(U) U+0308(Combining Diaeresis).

I think this information should be added to the readme somehow.
