haiku/headers/os/locale/UnicodeChar.h
Oliver Tappe 723383c0f4 Applied patch by PulkoMandy, adjusted and extended by myself: 
* integrating most of the locale kit into the build (and image)
* removed LocaleBuild.h and _IMPEXP_LOCALE since that does not make
  sense for elf (which usually exports all symbols anyway)
* added a couple of locale kit related pseudo targets for convenience
Hey, some of that stuff already seems to work :-)
