I of course never meant to imply it be used like that, that makes 
absolutely no sense.

Don’t TTF fonts provide a mapping of code points to glyphs? Surely they do?

How else would they cope with gaps in their character support (e.g. only 
latin-1 and symbols)? Store an empty glyph placeholder there? That seems 
awfully primitive to me. Anyways, if that is the means, there is no 
reason why a tool couldn’t replace the unused glyphs with an empty 
placeholder to reduce the size.
