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).
