I've been wondering about this for some time. I run a few non-english sites in languages that use some special characters like the letter ø. Now, how should I present these characters? Would it be preferable to use either ø or %c3%b8 in the content? My concern is primarily how SE's interpret these characters, when crawling my site. So far I've presumed both would work, but it would be nice to hear a few oppinions on the subject. Also, what would work better in URL's? Would /keyword-w%c3%b8rd/ work better, or should I just put it as /keyword-wørd/ ? I know Google encodes ø to %c3%b8 in their own URL's, and although it looks terrible, I speculate that this is the way to go. Up untill now I've just been using an alternate version (oe) in slugs. I'm not that concerned about being crawled - that works fine - but I would like to make sure that queries on wørd actually matches my content, as well as URL's, so any advice would be great. Thanks.
