Ligatures

I'm reading a PDF paper about ef ciency, with lots of de nitions, in the eld of lazy programming languages. It mentions the very rst Haskell compiler ever built and expresses the hope that the work will some day nd its way into domain-speci c languages.

Yeah. Something in the toolchain is clueless about ligatures. (Probably ps2pdf and/or pdftex.) I hope this bug eventually gets xed.
