Any idea how I can allow special characters like `curly braces` and `equal` `({}, =)`?

The IFBYPHONE analytics asked me to add this `?ibp-adgroup=Sample_Node_Title&ibp-keyword={keyword}&ibp-matchtype={matchtype}` in the URL after the node alias.

Ex: `http://mydomain.com/sample-node-title?ibp-adgroup=Sample_Node_Title&ibp-keyword={keyword}&ibp-matchtype={matchtype}`

But currently it is being displayed like this.

`http://mydomain.com/sample-node-title%3Fibp-adgroup%3DSample_Node_Title%2526ibp-keyword%3D%7Bkeyword%7D%2526ibp-matchtype%3D%7Bmatchtype%7D`

I just tried to add it in the URL Path Settings but the result is being converted to HEX character.

Any idea?
