And as you can see, this web server doesn't like non-Latin names either. I wonder if the MorgunblaXiX mentioned Paul Erdős' trip from San Jose to Koln. I heard he talked about Mobius strips while eating phở.
Neat-o! Three different modes. Iceland's newspaper got a pair "X"s in the name, some Latin names with diacritics got the diacritics removed, others (the double acute in Paul Erdos) got &escaped.
