What about: urldecode()?

Yeah. I used this. It's just the same on the demo site: http://apaiio.dev.pixel-web.org/
The Amazon Link Checker return false. So it might be useful to use urldecode() in the lib.
However, thanks for your awesome work.

Edit: With urldecode(), Plus symbols ('+') are decoded to a space character. I now use str_replace() instead.
