Virtual fonts and other related files for remapping the BSR/Y&Y/AMS Type 1 Computer Modern fonts; the remapping creates fonts which have no characters in the numeric range 0–31 (mod 128), and the virtual fonts map Knuth’s original encodings to the remapped fonts.

These mechanisms aid the production of robust PDF output from TeX-related systems, when they use CM fonts.

The original impetus for developing this bundle came from problems with Adobe Illustrator (hence the first two letters of the bundle name). Current versions of Adobe Illustrator can apparently use the CM fonts without remapping, so the bundle is not needed for such use.
