Can you give me an example of just running decodeURIComponent where it's not doing what you expect?

With your example I get:
```
// Espruino
>decodeURIComponent("PLUS%2B%2B%2B%2BLEER+++++OK")
="PLUS++++LEER+++++OK"
// Chrome
>decodeURIComponent("PLUS%2B%2B%2B%2BLEER+++++OK")
="PLUS++++LEER+++++OK"
// Node.js
> decodeURIComponent("PLUS%2B%2B%2B%2BLEER+++++OK")
='PLUS++++LEER+++++OK'
```
So I'd say it's behaving as expected.

However it's not desperately helpful for what you're trying to do. You could try decodeURIComponent(els[1].replace(/+/g," "));

Looking online it seems that is the accepted way of doing it: https://stackoverflow.com/a/24417399/1215872

That is exactly what I do to fix it but I thought that decodeURIComponent should already result the same.
It seems that it is my fault. Why are spaces something so special?

application/x-www-form-urlencoded Default. All characters are encoded before sent (spaces are converted to "+" symbols, and special characters are converted to ASCII HEX values)

I expected that a space would be
```
 U+0020		&#32;	Space
```
not just an "+".

Confusing for me :)

Thank you for your help!

PS: Espruino is very cool :)
