Would it be possible to get example links for testing? I'm asking because there are many *paths* the crawler can *take* and some *just eat* the url as it is, while others are processing them and replacing characters, eg space with %20 and so on.
The complex problem is that despite some characters are allowed in plain AND hex representation, some server do only accept one of both. That means for such a server it can happen that JDownloader has processed the *wrong* one first and then could no longer add the *other* link because duplicate check would detect both as same. And yes, there are servers out there that don't accept both representations
It would really help to get example links so I can test the several ways to add the links myself and check where the different representations happens and can try to fix/workaround the different ways so they end up as same/one representation.
