We just pushed out a major update to the back end of Newschoolers, which is designed to get rid of an extremely legacy problem with the Character set we used.
When you have seen broken/weird characters on Newschoolers, they are all caused by the fact that in 1999 Harvey chose one Character set, and it wasn't the one which got popular.
With this, you should be able to post all the weird characters and Emojis (or whatever) you want!
However, we'll need all of you to report anything weird you see that is broken. This was a monster update, and though it seems simple it literally touched every part of the code base. Expect a few bugs over the next week, we did as much testing as is possible but it is likely we missed a few things.
Report what you see in this thread, and please try to include a screen grab, browser type, OS, Device when you post!
