Bug#742767: TeX Gyre OpenType and wrongly(?) named glyphs

[karl@freefriends.org (Karl Berry)]

    as far as I understand it seems that at least Karl Berry agrees in
    that regard)

I hadn't realized that the ligatures only failed with non-fully-embedded
PDF's.  Such PDF's are inherently defective; it's been a long time since
Adobe recommended anything but full embedding (not that I think we must
kowtow to everything Adobe says, but anyway).  So maybe it would
actually be a good thing for ligatures to lose :), so that people fix
the PDF's where the problem originates

Just FWIW, I use the script below to embed PDF's that I receive
unembedded (generally graphics destined for TUGboat).

# ps2pdf is a front-end to gs. For a complete list of options, see
# http://ghostscript.com/doc/current/Ps2pdf.htm
#
# By default, gs encodes all images contained in a PS file using
# the lossy DCT (i.e., JPEG) filter. This often leads to inferior
# result (see the discussion at http://electron.mit.edu/~gsteele/pdf/).
# The "-dAutoFilterXXXImages" and "-dXXXImageFilter" options used
# below force all images to be encoded with the lossless Flate (zlib,
# same as PNG) filter. Note that if the PS file already contains DCT
# encoded images (which is possible in PS level 2), then these images
# will also be re-encoded using Flate. To turn the conversion off,
# simply remove the options mentioned above.
