Can't save scenes with apostrophes

Just upgraded to 1.0.423 and I get an error when saving scenes with an apostrophe in the name, for example: “I’m Home” doesn’t work but “I am home” does (this was fine in 1.0.320). I’m guessing it’s not properly escaped in the JSON request… can anyone confirm this?

I created bug report:

Our javascript dev will be back on January 2, and he can fix this before we do the release with the final videos
