That surely sounds sensible.

    Or in case a name is multiply qualified; e.g.,
              delta.sc.ipa         (occurs in  cmu-tipx.enc )   also
              omega.sc.ipa   q.sc.ipa   f.sc.ipa
    then drop off the qualifications from the end.
    So test in order:   delta.sc.ipa   delta.sc   delta

Ack.

Thanh, can you confirm that we should go ahead with this plan?

​I think it's reasonable to have this behavior possible.

However, Iet's say we have

\textsc{This is a heading}

What is the common expectation when one does copy/paste this text from a pdf viewer? 
I personally expect to get the same text, not the unicode points for the *.sc glyphs from the actual font.

This brings up another question: perhaps we can add the behavior proposed by Ross, but it has to be enabled explicitly via a primitive?

Regards,
Thanh
