A PostScript Font Installation Package Written in TEX Alan Jeffrey School of Cognitive and Computing Sciences University of Sussex Falmer Brighton BN1 9QH UK Internet: a1 an jeecogs. susx.ac. uk Abstract Ths paper describes a font installation package written entirely in TEX. It can parse Adobe Font Metric and Font Encoding files, and convert them into Prop- erty List and Virtual Property List files, for processing with pltotf and vptovf. Since it is written in TEX, it is very custornizable, and can deal with arbitrary font encodings, as well as mathematics fonts. Introduction The most important difference between ths package and other PostScript font installation packages (such This paper describes fonti nst version 0.19, a pro- as Rokicki's (1993) afm2tfm, used in Rahtz's (1993) totype font installation package for PostScript fonts psnfss) is that it is written in TEX rather than C, (or any other fonts with font metrics given in Adobe and so can be more easily customized by the user to Font Metric format). This package: deal with non-standard encodings and mathematical Is written in TEX, for maximum portabhty (at fonts. At the moment, only the T1 (Cork) encoding the cost of speed). is supported, but mathematical fonts will be added Supports as much of the Cork encoding as once an 8-bit font standard can be agreed upon. possible. Allows fonts to be generated in an arbitrary Usage encoding, with arbitrary 'fake' characters, There are four ways to generate fonts using the for example, the 'ij' character can be faked if fonti nst package: necessary by putting an 'i' next to a 'j'.
