hi could this just be the use of the font or asset_root interpolations? I don't 
know exactly what django templates are supposed to output in this case. I always 
just use preppy to prepare rml.

Have you actually saved the output that is produced from the template and 
checked it is all in utf-16. I think that means we need unicode as the django 
template output.

There's a bug in the current go method when saveRml='path' is passed in as it 
will try to save the rml with a 'w' mode argument and you'll just get an error 
there.

So you should probably save the produced RML yourself with a 'wb' mode argument.

I think this is almost certainly a problem in the content of the RML rather than 
an issue in the font itself. Missing glyphs should just appear as black squares 
etc etc.
