I hope so and I'm working on it -- with your help -)

Yes, here is what I have so far:

==============

Note the \rlap's (see attached pdf): we see that \tfx doesn't scale the \symbol, although \tfa and higher do work.

I guess fixing \tfx-symbol interaction will be part of your conversation with Wolfgang -)

> well, you wented symbols so

Ultimately I just want to be able to type the Unicode symbols for 02BE and 02BF -- ʾ and ʿ -- and get proper results. The overwhelming majority of hq fonts don't have them, and the few that do do them poorly, etc.

(So there is no substitute for full control of these transliteration characters.)

So even if we use symbols, would like to feed these setups to the CLD template you provided some days ago and feed the final result to \definefontfeature.
