It’s seriously broken!
Every country that doesn’t have letters not found in the english alphabet are fucked!
My name is Søren (the ø is basically oe) and Google+ has given me my danish name /sørenjensendk – which fucks everything up when trying to implement author markup…

Since this doesn’t work the following countries are fucked: Denmark, Sweden, Norway, Iceland, Greenland, Faroe Islands…. And probably every other country that don’t have A-Z alphabet.
