Re: Font rendering question - Apple Color Emoji.ttc

Hi,

Just following this up to make sure it isn=E2=80=99t forgotten. If =
it=E2=80=99s still in the to-do list and it=E2=80=99ll simply take time =
to look at it, no problem.

Thanks

To demonstrate, the following code attempts to use woman in a manual =
wheelchair, and then woman in a manual wheelchair facing right. The =
