I need to pass some parameters in the url and they can have special characters like , spanish Ñ or ñ, : spaces and accents.

What is the propper way to encode them before adding to the url or in case I got in the html like that, read them?

I tried this:

arrayData[i] = pair[1].replace('+',  ).replace('%22', );

But just get working with + or spaces, not both at the same time or in 2 lines:

    arrayData[i] = pair[1].replace('+',  );

    arrayData[i] = pair[i].replace('%22', );
