Plugin Issue Via API

[WarrenWich]

Hi.
I am having issues using this plugin via API.

Adding a URL with %20 into the web it works fine, but passing this same URL via API does not give the same result.

The URL does not have %20 in it at all.

Example:
Into the web - TSHIRT-2609%20ARFU%20WOLFPACK%20T%20SHIRT.pdf works fine
Via API - TSHIRT-2609%20ARFU%20WOLFPACK%20T%20SHIRT.pdf output TSHIRT-2609ARFUWOLFPACKTSHIRT.pdf

What do I need to do or change to get this to work?
