[pdftex] Re: (fwd) dvips/pdftex: font / buffer overflow

[Hartmut Henkel]

The point is, that you can obviously do things with `a' MAC or `under'
WIN, which you cannot do with `TeX', just due to such a minor
limitation.

One has to admit, that this chrimbobat font (legally) stretches the idea
of a `font' to its limits. It would better be an assortment of .eps
files. But still it has a letter (m) made by Erik Spiekermann, so it got
its blessings from a top-notch typographer :-)

If one increases this parameter T1_BUF_SIZE to 16384, it might work
well---maybe until christmas '03...

Greetings Hartmut
