[comp.text.tex] How can I get rid of Ligatures in plain.tex?

chiu@brahms.amd.com (Timothy Chiu) (02/22/91)

I'm typesetting a fairly lengthy document in plain.tex 
using an Adobe PostScript font (my boss refuses to let
me use cmfonts).

When I'm done, the document will be edited by people who
don't know the first thing about TeX so, I'm trying to
keep the formatting down to a minimum.  But because I'm
using an Adobe font, all "fi"'s and "fl"'s have to
be typed as "f{}i" or "f{}l", which is a real pain.  If
I don't type them this way they don't show up.  The 
equivalent of '014 and '015 in Times-Roman is a blank.

Is there someway I can turn off the ligature function in
plain.tex in a macro at the beginning of the document so
I won't have to type the "{}" (which is the workaround
D. Knuth suggests in the TeXbook)? 

Thanks!
