gcc on ubuntu (other linuxes?) does not support utf-8 identifiers

[hornc]

According to http://gcc.gnu.org/wiki/FAQ#What_is_the_status_of_adding_the_UTF-8_support_for_identifier_names_in_GCC.3F

and the issue tracking progress https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67224

Looks like the current method is to use UCNs: e.g: \uNNNN or \UNNNNNNNN syntax. We can perform a conversion somehow...

No idea yet how this worked in the gcc under OSX.
