White space value at the end of the URL causing ERROR

[Alberto Benatti]

Hi everyone, first of all thank you very much for this library which is really helpful!

I wanted to report an issue regarding the possibility to set a white-space value (' ') as the last url paramenter.
In fact if we insert the ' ' as last parameter is trimmed out and not considered. If we instead insert it not as last the library is working as intended.

We are using the Stringify to encode the url.
