Richard,
I had meant to ask you what M17n is?

It sounds as though you have a problem with your font compiler.  Are you not in control of how it converts substitution rules to the GSUB tale?

I may be worrying too much about whether the renderer will remove the glyphs derived from variation selectors.  Have you tried your font with M17n?
