In your first section, you tell the user 'Argument missing.' when they provide too many arguments. That's misleading, I'd change that to something like "Please provide only one URL" or similar.
In your Download() function, I see a couple things:
The toJStr() function is a bit suspicious, as it looks homegrown--like a "simple" task where you keep adding in exceptions as you find new ones. What happens if you get a binary string containing UTF-8 characters not in the ASCII range? Should your string be encoded?
One interesting thing might be what happens when you pass it something like "\00765". I didn't test it, but I'm thinking it's not going to end well.
The escape() and unescape() functions look unnecessarily opaque, and I worry that they may be homegrown things that don't have all the special cases handled. If they're "tried and true", you may want to mention that in a comment, as well as where they came from so you can treat them like "black boxes". That way, if some error occurs in the future, you can decide to dig into them or not based on your comment(s).
Also, why do you hate whitespace? If they were formatted better, at least you could look them over and get a feel for what they do.
Your Ceil() and Floor() functions are straightforward enough, that being one-liners seems OK. Even so, I'd still put a little whitespace in there for readability.
When your only tool is a hammer, all problems look like your thumb.
