Description must not contain special characters (Itunes Connect)

Question

I was able to submit my app to ITunes connect for review with a good description. When I took off the app so I could make changes, I tried to resubmit it hours later, with the same exact description, and now it says:

Description must not contain special characters (for example, null, new lines, carriage return, escape, and other invisible characters)

Is this a new rule for new apps just recently today?

Also, there is an error sign next to the Language setting, which I set to English.

---------UPDATE------

IT WORKS NOW! Finally. That was such a strange bug, especially since it was the first I ever encountered on Itunes connect.

Answer 1

This seems like a bug of iTunes Connect. Apparently it already happened once in 2010.

UPDATE: it was a bug, and it is fixed now.
