"line separator" (U+2028) breaks JSON

SUMMARY:
JSON output containing the special character "line separator" (U+2028) is 
rejected as invalid Javascript.

SITUATION:
A document copied and pasted from a word-processor may contain the special 
character U+2028 (line separator).   

If a post contains that character, a Blogger API query for a list of recent 
posts will deliver a JSON object with the character, unchanged -- that is, 
not 'escaped'.
Browsers reject the object as invalid Javascript.

TO REPRODUCE THE PROBLEM:

(1)  Create a sample post with this content:

"start
(U+2028 goes here)
end"

(See the attached file small-sample.txt.)

Copy and paste that file into the Blogger post editor (HTML mode) and save.


(2) In a Blogger widget, I request a JSON object: 

<script 
src="http://bistropha.blogspot.com/feeds/posts/default?alt=json-in-script&callback=document.write"></script>

This should write the JSON object to the screen.

(3) View blog.  Execution of the widget fails with no error message.

This snapshot from the browser's Javascript console shows an excerpt from 
the JSON object, with the line separator character before and after "start".

The error message "Uncaught SyntaxError: Unexpected token ILLEGAL" is 
generated by that line of the JSON object.

(4) To check the JSON separately, I ran
