strings, but "Line Terminators" which includes U+2028 and U+2029.

This pull request adds U+2028 and U+2029 to be escaped.
It's very common to see something like this in a Rails template:

If U+2028 or U+2029 are part of any attributes output in the to_json

In Chrome: Uncaught SyntaxError: Unexpected token ILLEGAL
# Why not?
This is JSON encoding, and the JSON spec is specific about how to
encode strings. U+2028 and U+2029 don't get special treatment.
Just trying to start a discussion... what do you do in your apps
to deal with this? Is there a convention I'm missing?
