Thanks. I don't mind the verbosity, but I could use some clarity:

There's been talk of LC using UTF-16 internally, but when I do this:

on mouseUp
    put "Hello" into s
    put the number of bytes of s
end mouseUp

...I get "5".

When does LC use UTF-16, and when it's not UTF-16 is it still ISO-8959-1 
or UTF-8?
