Yes, thanks - that is ideal!

So, it looks like we get the fallback with old versions of freetype,
and Preview has problems with the fallback. Things to do...

- it'd be nice to figure out if we can tweak the embedded font to
prevent the Preview problem; I'll still look into that, since it seems
I have a similar bug with atsui.
- Adrian, Carl - I presume there are some values of $version for
freetype where using the fallback is not considered a bug?
- However, it'd also be nice to know what version works correctly.
I'll install a few and find out.
- Mac users who have inherited this problem from Apple's X11 need to
install a more recent freetype to fix it for now - eg with macports,
'port install freetype' would do.
