I was running a small rails app and I got that error because of a character inside one class file. Below is the stack trace:

Attached is the source code of the app just in case it is needed. The offending file seems to be messages_controller.rb and the character is ˜.

It seems buffered logger's bug; it tries convert a string from ASCII-8BIT to UTF-8.
It should use force_encoding or output as is.

Or simply you use old sqlite3-ruby.
