Twitter cards inconsistently break encoding in Twitter feed preview


#1

Looking through my feed from a search query often incorrectly encodes accentuated and other special characters.

Example: http://cl.ly/image/1k2j2I1C0L1q

But when you go to the actual Tweet, https://twitter.com/joaovsantos/status/276634764490973184, everything looks good: http://cl.ly/image/0e1h0c3q233m

I haven’t found anything consistent about this behavior, but it has been seen in Chrome on both Windows and OSX. We also have users that have reported it from time to time, again with the usual “when you reload somehow it goes away”.

Help?
