I just ran into a smallish yet annoying font problem. After getting the Adobe Type Classics for Learning CD, I prepared a couple of fonts for work with ConTeXt. I was mostly successful. I wanted to have a Garamond with oldstyle figures as default, so I used a custom encoding vector; the only difference to texnansi was zerooldstyle etc instead of zero etc. This works well, but: in German, (mainlanguage[de]), I can't get the baseline double quotes to work. In the "normal" Garamond, "` in the source produces the desired result. In the oldstyle Garamond, I don't get the ligature (character 132 in texnansi), but instead what appears to be two commas juxtapposed. I assume this is some fallback defined somewhere. So the question is: what feature defines this ligature? It is language-specific and works only wihtin German text. And, more importantly: why doesn't this work with my modified texnansi-variant?
