"Invalid% coding" and "invalid byte sequence in UTF-8" increase significantly

I created a huge Rails application 2 years ago, which is the host on the Heroku cedar stack:

ruby '1.9.3'
gem 'rails', '3.1.10'

I use Airbrake to detect exceptions. Here is a list of unresolved errors created in the last 11 days:

As you can see, something is very wrong. Remote addresses are walls all over the world (USA, China, Italy, ...)
