UTF in RSS?

I'm trying to read from an external RSS feed and display the results
on my site, but I'm getting weird characters in places. This looks
like a charset mismatch (ie, the feed in question is utf-8, but I'm
not?), but I'm not sure how to fix it?

At the command prompt, mysql shows the appropriate character (ie,
fancy apostrophe, not binary or weirdness), but console shows a weird
binary-ish string, like "more evidence of the housing
market\342\200\231s deceleration". That makes me think the problem is
in Rails/Ruby somewhere?

Or: is there a way to strip this out or replace it during the RSS
parsing? I don't so much care whether I show the fancy quotes or not,
I just don't want the junk characters.
