I looked around and can't find any info on this, I must be searching the wrong terms or something because it must be a common question.
If you have non-ASCII characters in your URLs, Firefox and Chrome show them nicely in the address bar (like en.wikipedia.org/wiki/Cliché), but IE (including IE10 consumer preview) shows a munge of character codes or something, like this en.wikipedia.org/wiki/Clich%C3%A9.
Is one of these approaches more correct than the other? Is it likely that IE will one day start doing what FF and Chrome do?
Basically I'm trying to decide whether on a new site I should transliterate or not. My preference is to not transliterate, because it "seems right" to use the correct characters and it looks better in FF/Chrome. However, it looks horrible in IE, and since the majority of people use IE, that argues for transliteration.
Once you put a policy in place, you're probable never going to change it. So if I know that a future version of IE will start acting like Firefox et al, then I'm happy to lay the foundation with raw URLs and let current users suffer. But if not, I think I'd prefer transliteration. Any recommendation?
