Hello,

I found another problem in glyphtounicode.tex file. There are duplicate 
codes for ligatures, see:

\pdfglyphtounicode{ff}{FB00}
\pdfglyphtounicode{ffi}{FB03}
\pdfglyphtounicode{ffl}{FB04}
\pdfglyphtounicode{fi}{FB01}
...
\pdfglyphtounicode{fl}{FB02}
...
\pdfglyphtounicode{IJ}{0132}
...
\pdfglyphtounicode{ij}{0133}
...

...
\pdfglyphtounicode{ff}{0066 0066}
\pdfglyphtounicode{fi}{0066 0069}
\pdfglyphtounicode{fl}{0066 006C}
\pdfglyphtounicode{ffi}{0066 0066 0069}
\pdfglyphtounicode{ffl}{0066 0066 006C}
\pdfglyphtounicode{IJ}{0049 004A}
\pdfglyphtounicode{ij}{0069 006A}

Currently pdftex use last defined value, so first definitions are 
useless. Can you fix it that file, so there will be only one active 
definitions? I see that on other places duplicate values are just 
commented...

And why is used decomposited sequence of ascii for those ligatures 
instead using unicode character for each ligature?
