In June 2014 there was a thread on accents in URLs not working in the RISC OS NetSurf. That thread has expired here so I need to start a new thread just to say the issue is now fixed in #2859.
http://bugs.netsurf-browser.org/mantis/view.php?id=2137 The URLs were:- http://dahlström.net or http://dahlström.net/svg/favicon/favicon.html (In the event of character mangling that's o-umlaut, alt-246.) My thanks to the NetSurf developers. -- David Pitt
