If I understand the OpenType standard properly, it is supposed to do most of
this automatically (it seems to in some applications, but I am not sure
whether it is the font or the application doing the work). The question may
actually become how to turn it off if you don't want it. See Section 7.8.1
for a discussion of how this ties in with XSL-FO. This is one reason why I
am working on trying to get our font support upgraded to handle at least
OpenType fonts that are registered at the O/S level (see the "fonts" thread
over the past few days). In the meantime, and for other font types, I
suppose a lot of this could be done with some regular expression
preprocessing -- it might even be possible to do this within the parser or
XSLT transformer.
