Recapitulating

Recapitulating

[Pepe Barbe]

After jumping through hoops, with some help I managed to get XeTeX
running and using TTF fonts directly with pdfTeX.

But before I go any further I would like to know what is your opinion
in using one or the other. When researching a bit on XeTeX I read
there were several caveates vs. using pdfTeX with LaTeX.

Is this the same? In ConTeXt. What can I expect to work and what not?
If TTF can be used with pdfTeX (with some effort) what is the
advantage of using XeTeX with ConTeXt?

Thanks,
Pepe

In contrast to LaTeX where many packages are specifically written for
pdfTeX and for pdfTeX only (or dvips and dvips only) and not
maintained any more, so you can't use them at all (unless/until
someone writes a new XeTeX-specific package, but it's still very
unlikely that one could use PSTricks in the near future for example).

ConTeXt should be much more transparent to the user in the sense that
in most cases you don't really have to care whether you compile a
document with pdfTeX or XeTeX (you don't or at least shouldn't need to
change your documents at all apart from some font definitions).

For me the major drawback until today was that I wasn't able to
include figure (now I can do that).

Apart from that the only thing that comes to my mind is the usage of
(math) fonts in general. XeTeX has not been around for such a long
time as pdfTeX, so if you want to set up your own font for math or
whatever, you might need slightly more patience. (Latin Modern hasn't
been set up yet to work in the same was as it does in pdfTeX for
example.) And if you want to use the old TeX fonts, you might come
accross some problems with accented letters (XeTeX doesn't know that a
certain font is ec-encoded) ... etc.

But well ... if you managed to get your favorite fonts working in
pdfTeX and if you don't need Vietnamese, Arabic or other exotic
letters, scripts or fonts, you don't really need XeTeX. pdfTeX will be
considerably imroved pretty soon as well.

To conclude it in two sentences: concentrate on content instead. You
would have to think twice if you would have to decide between LaTeX
and ConTeXt. The difference between documents in pdfTeX and XeTeX is
only a matter of a couple of lines in setup, "nothing more".

math is a different story

- more that 16 families
- unicode access > 64K (where math is located)
- additional (and alternative) symbol definitions
- new (!) math features built into the engine

pdftex and xetex are currently more or less the same; things may become 
different when open type math fonts show up

i also expect pdftex 2 (aka luatex aka metatex) to provide new 
functionality, but much of that is hidden for the user and aimed at 
better output

so, when you use pdftex and xetex mixed, you must keep in mind that the 
same text may be typeset diffferently due to different font handling and 
features

by the end of the year / begin next year, pdftex will support open type
natively 

xetex uses libraries and hooks into platform font support; pdftex will stay independent of libraries and focus on extendibility and configurability (think of scripts that demand complex solutions and different ones as well, like arab); of course the question is if in the end it makes much difference for the average user 

concerning context and these two ... we may end up with a common core and different subsystems and levels of support; graphics for instance can be dealt with in a way hidden from the user, as can input encodings; fonts and font features may differ but i'll try to offer a kind of generic interface to for instance open type features since the definition and control of fonts will differ per engine

of course it also depends on what i use (most) and what users demand -)
