    libraries/base/GHC   Unicode.hsc Unicode.hi-boot 
  Log:
  Use the wide-char classifications from the C library if available.
  This gives us Unicode-aware isLower, isUpper, isAlpha etc.
  
  On Unix, you have to set your locale to something.  This is usually
  done by setting the environment variable LANG, eg.
  
    export LANG=en
  
  This stuff *should* also work on Windows, except that Windows uses a
  16-bit wchar_t so will get it wrong for characters > '\xffff'.  However,
  I figured it was better to use the system-supplied functionality
  rather than trying to implement this stuff ourselves.
