There exists a non-breaking space:


Perhaps you could use this. In R on Linux under gnome-terminal I can 
enter it with CTRL+SHIFT+U00A0. This seems to work: it prints as a 
space, but is not equal to ' '. I don't know if there are any 
difficulties using, for example, utf8 encoding in source files (which 
you'll probably need).
