Anyway, in the next context distribution upload (context also ships

Great, that looks really good!
What I still do not understand is why it is needed to specify enc=csr.
Encoding vector is present in PFB file.
because the order in a pfb can be different and there can be more than
256 glyphs in a pfb ... the glyphname is what links them
index in tfm -> name -> index in pfb
Also, I have another question, is there ability to load PK font file
(generated from MetaFont)? Specifying metric file (tfm) and encoding
vector (enc) should work similarly (or maybe same?) as for Type 1 PFB
font.
sure, i can do that (omitting the pfb entry will then revert to bitmaps
plus a bit of safeguarding against inconsistent names and so) but keep
in mind that a mixture in one document will then always use the outline
(as the map entry wins)
(It uses a few helpers from the existing font code, like cached
loading and glyph names to unicode mapping using the enc file which
saves resources and is also more generic than hard coded font
vectors. It's still a pitty that these csr fonts don't come as a
full package like plr which has afm files too; in which case the
regular afm/pfb loader could be used instead. I only tested
csr10.tfm / csr10.pfb / css.enc as I don't want to install the whole
lot.
If one is working, others must too.
Where I can find your changes, so I could test it? Ideally if I could
download tex/lua files into working directory and use system luatex
instead building whole texlive and luatex from some sources...
you have to wait till i update context and then fetch it from the
context garden (i'll update later today)
