Rails - May 2012 - how to not encode only one attribute of model when calling render :json => model

Cross post from SO, hoping to get more insight here.

I''ve got a column called message in one of my model (UserMessage) in
rails. Now message can contain emoticon value which I passed in from
an iphone app.

For example, the smiley icon has the unicode value of U+1F604 and
since it''s passed in with json format, it''s serialize to
"\u{1F604}"
in my database (postgres).

Now all is fine until I call render :json => @user_message in my
controller. Rails take the serialized message "\u{1F604}" and call
ActiveSupport::JSON.encode on it and therefore encode it again. I''ve
try to override to_json in the UserMessage class to no avail.

Can someone please point me to the right direction?
