Here's a fix for the "N9 eats Emoji SMS silently" bug:

The Emoji SMS Fix consists of a patcher utility and a drop-in library that can
be used to fix a bug in libsms-utils, causing incoming SMS containing Emoji
characters to be silently dropped.

Thanks to Jonni for the initial inspiration and some pointers.

This fixes delivery of SMS to the SMS application. For actually displaying
Emoji, you need to install Harmoji, which includes suitable fonts.
