You mean like: t^^^^200dh^^^^200de

Doesn't work, not in Jaguar anyway.

You're surmise was correct that ZWNJ does work though.

That's a fine distinction I'm often forgetting to make. Sorry 'bout 
that.

Okay, feature request then, a mechanism to request ligature variant 
<foo> for character string <bar> (there're a couple of ligatures w/ 
variant forms --- gg, and ll if memory serves).
