Roundcube does not fully recognize URLs with 8bit chars, they are being truncated upon the first occurrence of any such 8 bit char. But much to my surprise, they do exist and they do work - at least in FF 27.0.1. For instance this one:
http://suchen.mobile.de/auto-inserat/bmw-335i-a-navi-prof-hifi-h-k-el-glasda...
???
(And no, I didn't buy the car... ;))
