No way. It's perfectly valid. I just tried and uploaded http://commons.wikimedia.org/wiki/File:%C3%89%C3%A9%C3%A9.jpg as expected, without issues.
I also tried with "[[É]].jpg" (the brackets are illegal in the names) and I get a warning saying that the name has been changed to "--É--.jpg" with three buttons, and them indeed fail.
Thanks for testing -- from memory, the name was something like
"Le_ Musée_ Libre_ présente Wikimédia Commons..."
So maybe that was the length, the "_" char -- or whatever.
It proceeds had you originally chosen 'Ignore any warning', though.
I've been using the upload wizart: where is this option?
I have opened a bug at https://bugzilla.wikimedia.org/show_bug.cgi?id=33357
Although I'm not sure if that's exactly what you experienced or a different one.
I'm not sure either. Thanks for the bug report.
