As for now if you are using APP print engine with Arbortext Styler hyphenation will occur after specific hyphenation characters. There is no available options to change the hyphenation to occur before the hyphenation characters. This makes linebreaking in URLs to occur in a bad way. If there is a dot in the URL and the linebreak occurs right after that dot it will sometimes look as if the URLs ending is at that characters when it actually contiues on the following line.
It's a usual recommendation to have the linebreaking occur before characters as dots, slashas, hyphen and other similar characters when it comes to URLs. This should be supported in a profesional product like Arbortext Styler.
