> Which is why you always type out addresses in ASCII representations in any foreign transactions even if it's not going to match your identity documents, unless the other party specifically demands it in UTF-8 and insists that they can handle it. That is not always possible and the translation from local writing system to ASCII is often not unique and ambiguous. There really is no excuse for this sort of thinking. Even American programmers have to realise at some point that programs serve some purpose and that their failure to represent how the world works is just that: a failure. There is no excuse for programs to not support UTF-8 from user input to any output, including all the processing in between.
