I'm assuming he's actually referring to the URL. It's definitely debatable. The URL shows up correctly with accents in browsers like Chrome/Safari and Firefox. It doesn't in IE. I can make it show up in IE by not URL encoding, but that's not valid and there's at least one place in XF that falls over because of that.
Yes ... I was referring URL, sorry.
Only IE doesn't show the proper letters with accents and as a vBseo user I'm accustomed to see accents replaced by the correspondent letter.
For me, if Google spell it right and doesn't use the "IE version", I'm ok with that
