> I think there are unsolved issues. Now there are two methods

> (b) \pdfgentounicode, glyphtounicode.tex
> 
> Both methods have its limitations, e.g. (b) only works for Type 1
> fonts.  Thus you could need both methods to cover all fonts, but the
> methods doesn't know each other, thus fonts can end up with two CMap
> tables.

Message:
a workaround for this problem is available in pdftex stable (1.40.11-beta). A
primitive was introduced to disable the tounicode entry generated by
\pdfgentounicode if needed. Minimal test file:

,--------,
\pdfcompresslevel=0
\input glyphtounicode
\pdfgentounicode=1
\font\f=cmb10
\pdfnobuiltintounicode\f
Hello, \f world!
\bye
