Yes. I think this is part of it. Here are the logs from a few weeks ago: http://j.mp/pBqfbx I'd be curious if anyone can figure out why so many visitors are using a browser called Netfront (apparently from Samsung mobiles).
On my BlackBerry, inadvertently swiping the trackpad while typing a vowel results in an accented version of the vowel. There might a similar mechanism at work in Samsung devices.
I see. What is interesting is that most of the requests come from Samsung devices in Spanish-speaking countries, so I guess their keyboards must make it even easier to make the mistake.
