Several people have been having problems with posts that contain unicode characters. It turns out that I broke unicode support in the UI update. Forms were passing bad data back to the system when submitted. In our HTML code, this:

<meta http-equiv="Content-Type" content="text/html; charset=utf=8" />

Should have been this:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

Oops! My bad. :)

I didn't catch the typo when proof reading the diffs. The problems should go away now. If they don't, let me know...

On the bright side, in the process of debugging the problem we added in better logging capabilities for tracking situations where the code errors out.

There still appear to be problems with some posts when forwarding to multiple users. Those problems have been around for awhile.. They are going to be worked out in a forthcoming update to the posting interface.
