[lltx] luaunicodespace module

[Khaled Hosny]

Hi all,

Getting bored of hacking fonts, and inspired by a discussion on XeTeX
list, I wrote a small lua module that tries to handle the various space
characters defined in Unicode and convert them to something TeX
understands.

The code is here:
https://github.com/khaledhosny/luaunicodespace

It reads the node list and converts the space characters to glue nodes
and penalty nodes if necessary. It is just a proof of concept, and need
to be extended a bit to be more useful, if there is an interest in it.

Regards,
 Khaled
