In general all shapers need to be handle any characters fed to them, at
least in a simplistic fashion because there is an actual need to feed
neutral characters such as white space, zero width marks, etc to the
shaper handling the adjacent text.

I'd really love it if someone could take a look at this bug and figure
out the right fix.
