Symptom:
A program that ran fine on my iPhone- after being copied to Dropbox and then to my iPad - would not run! Ton, this may get your attention. Dropbox had converted many special characters to their html equivalents! So & became & - > became > - < became < and so on.
Of course every such change resulted in a program termination with a syntax error.
I couldn't believe it had actually happened, and thought I had copied the wrong file. So I went through the entire process again and got the same result. Just as when Apple changed our standard quotes and apostrophe in iOS 11, I'm sure we will soon be able to search the web for and find discussions of this phenomenon.

Ton, we should be able to counter the problem by using your Clarify code.sb to convert the html back to the standard characters.
It would be helpful for others to test this issue and report on it if you have upgraded to 12.1. I plan to copy a working program on my iPad to Dropbox and from there to my iPhone - to see if the html substitution occurs in that direction too.
