"Bruce D'Arcus"
make use of the "Virtual Fonts" feature in TeX and the backends. How did you install your fonts? You should have some .vf files for your fonts and you can access the contents of them with vftovp (convert back with vptovf) and just add ligature information.
The strategy he used does not use virtual fonts.
Who is "he" in this case? Adam?
It involved running afm2tfm (via texfont) on the afms to extract the glyphs using different encodings.
But afm2tfm gives you the vf's! And how can you reencode a font without vf's? Are you doing this in the mapfile?
Conceptually this is pretty straightforward. I'm not sure (because I've never done it) what would be involved in extending this installer to support adding ligs via vfs...
Just take the fi as an example. Patrick
