pdfTeX offers fine tuning of:
(1) Character protrusion
(2) Font expansion
(3) Tracking
(4) Additional kerning
(5) Interword spacing
AFAIK ConTeXt covers 1+2+(3?) ...
Are there any plans to cover the rest?
My concern was based on this introduction (on title page), especially on that
sentence marked with asterisks:
<cite>
Note that character protrusion requires pdfTeX (version 0.14f or later),
LuaTeX, or
XeTeX (at least version 0.9997). Font expansion works with pdfTeX (version 1.20
for
automatic expansion) or LuaTeX. The package will by default enable protrusion
and
expansion if they can safely be assumed to work. Disabling ligatures requires
pdfTeX
(≥ 1.30) or LuaTeX,
************************************************
while the adjustment of interword spacing
and of kerning only works with pdfTeX (≥ 1.40).
*************************************************
Letterspacing is available with pdfTeX (≥ 1.40) or LuaTeX (≥ 0.62).
</cite>
protrusion and expansion are supported at the luatex engine level but
configuration is up to the macro packages and they can follow different
approaches
the other things ... well, they are up to the macro package
3 - i have no clue what tracking is
As explained in that document this seems to be a synonym for letter spacing,
which is IMO supported.
yes, context supports that (more than just letters)
4 - neither what additional kerning is (unless you mean (usually ugly)
extra inter character kerning, which is supported)
Rereading the description in that document there is no advanced processing
behind it, so most likely just that ugly kerning, already available in ConTeXt.
Just curious why not mentioned as supported on the title page.
what title page? anyway, one can kick in extra font features to deal
with kerns (although when a font is that bad i'd use another font)
5 - it being a rather core tex feature, normal interword spacing is
supported
This seems to be a standard glue with plus/minus value. Again, curious why not
mentioned as supported on the title page.
probably because it is so standard
Are you aware of any typographic feature which is available in pdfTeXt, but not in ConTeXt?--
pdftex is an engine so even if something is available it has to be
supported by macros
i don't think that there are typographical advantages of using pdftex
over luatex (at least not with context)
