<ATTN task force> LaTeX's T1 encoding / LaTeX PS fonts

Hi everybody,

Attached are two files, that together should allow Context to use the
psnfss virtual fonts from a 'standard' TeX installation instead of the
texnansi encoded fonts. I don't see a good reason why one would want
to do that, but it was easier to create these files than to create a
distrib of the needed metrics for LY1.

Notes: 

a) would someone please verify that this works on a virgin 
   context installation? (mine is too weird for that)

b) fontec.tex is an example file. Hans, could you please look at it's
   preamble to see if I missed something (had to patch context to get
   this to work...)

c) font-ber only works for Times/Helv/Cour. If anyone knows the other
   metric file names, please post them.

d) enco-ec has a trick to use pre-built '\c c'. This could be applied
   to the other font encoding files as well.

e) if anyone needs the tie accent, please let me know how to code it...

f) enco-ec.tex also supports \k from LaTeX (the ogonek accent)

g) eng -> \ng 
   Eng -> \NG
   eth/thorn -> \th
   Eth/Thorn -> \TH
   dutch ij -> \ij
   dutch IJ -> \IJ

h) of course no \dotlessj unless you patch the vf files yourself,
   and no prebuilts either, but this is normal for PS fonts

i) Hans, can the '\"{a} => because of braces always \" in 7t encoding'
   quasi-feature be safely removed? It's the silliest thing in context
   I've seen so far...

Greetings, Taco

%D This is \LaTeX2e's T1 encoding vector, which 
%D seems to be popular with certain people. All standard
%D \LaTeX\ accents will work, including \type{\k}. The only accent
%D that does not work is \type{\t} (there is no tie in T1 encoding).
%D 
%D Annoyingly, most PostScript fonts do not have \type{\dotlessj}, 
%D and T1 encoding does not make the various prebuilts with
%D \type{j} available.
%D
%D There is hardly a point in supporting TS1 encoding. 

\startmapping[ec] 

%D the case mappings are fairly simple. Perhaps there is a shortcut
%D to do this?

Glad somebody is pleased...

These are on purpose. d' == dhacek&&dcaron and l' == lhacek&&ldcaron,  
both have a changed hacek/caron to fit in the line (traditional)

    Erik> \=d yields a d with a dash that collides with the stem. \= b
    Erik> and other "tall" characters look fine with the dash somewhat
    Erik> above the stem

\=d is dcroat&&dmacron&&dbar, using the same logic.

    Erik> What is "t: \t ae" supposed to yield? I get simply "t: ae".

It's the (totally missing) tie-after accent (texbook p52)

I've just installed Linux on a new machine.  Thus I'll be able to test
this on a virgin/latest ConTeXt installation within the next couple of
days (as soon as I've looked into one or two networking issues...)

The important thing about this patch is/was the enco-ec.tex
file. After Hans & I have sorted out a few minor glitches, it will
move into the core distrib.

Not for this berry stuff, that is part of any standard tex distrib.
And since you & me are probably the only people that use and have the
texnansi tfms, I don't see a real reason yet. If and when we create a
distribution for texnansi tfms, we definately should. But I am not in
a hurry to do that...

This is why I asked for the names for the other fonts. At least the
base35 (but preferably all of the PS3 ones) should be in there and
correctly named. But I no longer have those files (trying to cut down
hd space), so I depend on other people to tell me what they are called
(the proper psnfss name for the 8t encoded version, that is).

Hm. One can use filemapping to use other names, so it is under your
control. Currently the method is: 

(1) define font in terms of Regular/Sans/Mono)
(2) map those on verbose names, like TimesRoman
(3) map these on filenames 
(4) if needed remap these names (and so on)

Step (3) happens in for instance font-ber; this means that a different
local mapping can be acchieved by overloading this file. The file
font-fil maps to original filenames and does not use virtual fonts. The
advantage of this approach is that one can stick to logical names
(Regular). So, 

  \font\test=\truefontname{Regular} at 12pt

or 

  \definefont[test][Regular sa 1.5] 

gives the main regular body font. This is an advantage in defining
styles. Some special ones, like OldStyle and Gothic are defines using
this mechanism. 

Defining a new fontset is not that hard: 

Mapping names (Serif is equivalent to Regular): 

  \definefontsynonym [Serif]            [AntykwaTorunska-Regular]
  \definefontsynonym [SerifBold]        [AntykwaTorunska-Bold]
  \definefontsynonym [SerifItalic]      [AntykwaTorunska-Italic]
  \definefontsynonym [SerifSlanted]     [AntykwaTorunska-Italic]
  \definefontsynonym [SerifBoldItalic]  [AntykwaTorunska-Bold]
  \definefontsynonym [SerifBoldSlanted] [AntykwaTorunska-Bold]
  \definefontsynonym [SerifCaps]        [AntykwaTorunska-Regular]

Defining the whole set, based on the default relations:  

  \definebodyfont [14.4pt,12pt,11pt,10pt,9pt,8pt,7pt] [rm] [default]

Mapping the names onto files: 

\definefontsynonym [AntykwaTorunska-Bold]    [anttb]
\definefontsynonym [AntykwaTorunska-Regular] [anttr]
\definefontsynonym [AntykwaTorunska-Italic]  [anttri]

So, there is only one place where the filename comes into focus. 

BTW, Defining those non native (vf) fonts always was (and still is)
beyond me because I have only one set of times files and, using
dvipsone/dviwindo, cannot test virtual fonts at all. Some day --when I
got this new big laptop-- I will install more fonts and metrics and
viewers and start testing this. Until then I completely depend on others
for testing. 

BTW, does anyone know what encoding the antikwa fonts use? Seems like a
useful one (poland + neighbours). 

> characters instead of ligatures ff, fi, fl or funny characters instead of quotes.

This reminds me of the time we started using a ps printer, windows +
dviwindo, dvipsone (ps) and at the same time mattes viewer. I never
found out why windows remapped fonts, but I got it working and since
then never changed my tfm/pfb/etc files. Acrobat was yet another pain,
because it optimized some glyphs into the void (spaces and quotes) but
there was a workaround for that. 

> But never everything correct at the same time.

This is an encoding issue and related to the previous. We use times a
lot (tir files) and never had those problems, but I think your problem
could have been due to missing texnansi tfm files. Taco once suggested
to set up an archive for this (if only because texnansi is a rather good
encoding).  One reason for using the tir ones is (was) that I dislike
those (sometimes even) changing berry names, and prefer originals.  It's
also the reason why I have my own mapping files (taco, should we also
provide a map file?).

Good to hear that! 

Since the names in font-ber change now, we must make sure we make the
right choices once and for all (that is: taco makes the choices -). Some
time ago I got some baskerville fonts needed to typeset some UKTUG
stuff, and ended up with 5 subdir with 5 sets of tfm files and I never
could sort out which one to use, especially because the names in the map
files were yet another set.

Hm. v+d is mapped directly to a glyph, so this is a characteristic of
the font used. I just changed the underlying code to always prefer the
direct glyph (instead of falling back on the plain method when using
{}). 

BTW, the next release of context will have \showencoding, that shows a-z
combined with accents and also shows (in color) if they are composed or
not. Maybe that helps.  

For the curious ones: watch the pdf sections in the encoding files.
These make sure that as good as possible characters are mapped onto
pdfdoc encoding. So we have several mappings: glyphs, lower- and
uppercase, output encodings like pdf, etc.

These are the abbreviations for corelpak fonts. The notation and tfms/vfs 
are work-in-progress, but just to give you an overview here you are 
with a preliminary version.

Argument 1 is the kb font name, #2 the family default for LaTeX, #3 a 
list of informal font names ("original" and bitstream names), and #4 a 
list of activation commands for non-default styles/family variants.

The font encoding stuff is ready, but I am still working on the macro

Until now always had problems with Times: first ConTeXt seems to insist on
using tir.tfm, etc., then I get problems with either missing accents or funny
characters instead of ligatures ff, fi, fl or funny characters instead of quotes.
But never everything correct at the same time.
Maybe I'm stupid, but anyway I for one am VERY happy to see that this new
method actually WORKS for me.

I noticed a few strange characters in Taco's example, but maybe that's on
purpose:
- \v d yields d'
- \v l yields l'
- \=d yields a d with a dash that collides with the stem. \= b and other
  "tall" characters look fine with the dash somewhat above the stem

What is "t: \t ae" supposed to yield? I get simply "t: ae".
