Hello,

Jonathan has already answered the question, but one more observation
for the others - in ConTeXt we felt that some of the ligatures were
sensible (namely, three of them - endash, emdash and apostrophe),
while the others (like `?) are more like leftovers that are not really
desirable/needed in Unicode world, so we added additional mapping to
the ConTeXt distribution (loaded automatically when one uses
"features=default" in high level user interface). That mapping only
uses the three above mentioned ligatures.

Anyone on this list sharing the thoughts? (It might make sense to have
another common mapping apart from tex-text.)
