You are using --url-encode wrong, please review the documentation [1].
Use it once for each name=content, and also use it only when the data
isn't already encoded. (Maybe the docs could be clearer here?)

In a windows batch file if you split that form over multiple lines it
looks like this

curl ^
   --data-urlencode "x=3910CD8F" ^
   --data-urlencode "super=" ^
   --data-urlencode "captcha=I am a human!" ^
   --data-urlencode "submit=Click to download =BTC= Militia" ^
   http://website

The reason %21 in a batch file causes a problem is because windows reads
it as %2 (the second argument passed to the batch file) and then the
number 1. So it would become "I am a human1" assuming there's no second
argument. Tricky. I use percent symbols as little as possible.

There is another problem though which is the website you are trying to
access has some countermeasure to prevent scripted downloads. Your best
bet would be contact the webmaster and ask for permission.
