Actually, I meant Uniscribe.

As you may have seen, I've started creating awareness for the migration
to Unicode from existing short-circuit implementations in which Latin
glyphs are overridden based on arbitrary keyboard layouts.

To do this, I've provided some sample materials on my website [1],
posted some short text on G+ with font download link, targeting
general users (in my circle).

Thanks! I've got some GDL documentation from Martin for some time, but
still haven't read it. Currently, I'm focusing on input method design for the
Lanxang project [2], as the font has been ready at some degree.
I'll get back to refine Khottabun font afterward, and certainly can benefit
from your work!

OK. I'm just taking an opposite approach, to tease people first.

PS. I've Cc: Hariphunchai list. Let's continue our detailed talk there,
to avoid spamming Harfbuzz people.
