Indeed, your answer made me check back old documents I had printed.
The comma apostrophe was there! When you don't think about those
things, you never realize them...

So I checked back a bit, and what is wrong then is not my input per
se, but my current document setup, which I don't know how to solve.

Two weeks ago, I asked about OpenType features. Mojca and Wolfgang
thus gave examples of \definefontfeature. So, since I wanted to try
out the historical ligatures in my font (dlig) alongside oldstyle
nombers, I used the following, based on what I was told:

\definefontfeature
 [myfeatures]
 [method=node,script=latn,language=dflt,liga=yes,onum=yes,kern=yes,dlig=yes]

It turns out this is the culprit. When I comment that out, the comma
apostrophes are back. :-)

This makes me very happy because after all I won't use the historical
ligatures. Therefore, I can use the oldstyle feature set and
everything works well.

That is not to say that wouldn't like to know how to solve what
happened though. For the sake of it (and some eventual document's
where this will be crucial), I would like to know what do I need to
add to \definefontfeature for the apostrophe magic to work?

Thanks!
Jeff
